Judicial review in Brazil is governed by a combination of general constitutional principles and remedy-specific regimes. At the general level, the 1988 Constitution guarantees access to the courts, due process, equality, reasoned decisions and legality in public administration, while the Civil Procedure Code provides the default procedural framework for ordinary judicial challenges. In parallel, Brazil has a set of well-established special remedies for public law disputes, including mandado de segurança (writ of mandamus), popular action, ordinary action, public civil action, habeas data and, in constitutional matters, direct actions before the constitutional courts.

In practice, the applicable route depends on the claimant, the type of right asserted, the evidentiary record and the authority that issued the act. There is also a federal administrative procedure statute for the federal executive branch, and states and municipalities often have their own administrative process rules. The result is a system with strong common constitutional foundations but multiple tailored procedural avenues.

The competent forum depends mainly on the public entity involved and the nature of the dispute. Challenges against federal authorities, federal agencies and federal state-owned entities are usually heard by the federal courts, while challenges against state and municipal authorities are generally heard by the state courts. In both systems, cases normally begin before a single judge and may then move to appellate courts.

Specialised jurisdictions may apply where the underlying subject matter so requires, such as labour, electoral or military justice. At the apex of the system, the Superior Court of Justice deals with federal statutory issues and the Supreme Federal Court deals with constitutional issues, including direct constitutional review. For some state and federal norms, concentrated constitutional review may begin directly before the Supreme Federal Court or before the relevant state court.

In recent decades, the courts of accounts – which are linked to the legislative branch – have expanded their role well beyond the review of public expenditure. They now also assess the legality and efficiency of administrative acts and regulations, often within a broader scope than that typically exercised by the judiciary. As a result, they have become a forum as relevant as – and in many cases more relevant than – the courts for complex administrative disputes, although their decisions may still be subject to subsequent judicial review. This is especially true at the federal level, where the Federal Court of Accounts (Tribunal de Contas da União – TCU) exercises external oversight over public administration.

Susceptibility to challenge is determined by both the status of the decision-maker and the nature of the act. As a general rule, Brazilian administrative law review is triggered when a person or entity is:

• exercising public powers;
• performing a public function;
• applying administrative sanctions;
• conducting procurement;
• managing a concession; or
• otherwise acting under a public law regime.

That means the same entity may be reviewed differently depending on the context. A state-owned company, a concessionaire or a professional council may be subject to public law challenges when exercising delegated authority or performing a regulated public function, but disputes arising from purely commercial activity will usually be examined under private law rules. Courts therefore look beyond labels and focus on the legal regime and effects of the challenged measure.

Standing to bring such challenges varies according to the type of action. Individual claims are generally available to parties directly affected by the challenged act, and typically produce inter partes effects. By contrast, certain constitutional and collective actions may be brought by a limited set of institutional actors (such as the Public Prosecutor’s Office, political parties, Bar associations or other entities with statutory standing) and may produce erga omnes or broader binding effects, depending on the procedure avenue and the nature of the decision.

Primary legislation may be challenged on constitutional grounds.

Brazil has both concentrated and diffuse constitutional review. In concentrated review, certain constitutionally qualified actors may file direct actions such as an action for unconstitutionality, a declaratory constitutional action or an action for breach of a fundamental precept before the Supreme Federal Court. State constitutions also allow the review of state and municipal norms before state courts in some circumstances.

In addition, the constitutionality of a statute may be challenged incidentally in an ordinary case. The main grounds are formal or substantive unconstitutionality, including lack of legislative competence, procedural defects in enactment, violation of separation of powers, federalism, due process, equality, proportionality, legal certainty and other constitutional guarantees.

Secondary legislation such as decrees, regulations, resolutions, ordinances, tender documents and other normative acts may be challenged for illegality and for unconstitutionality. This is a common form of public law litigation in Brazil, particularly in regulated sectors and procurement disputes.

The usual grounds include:

• lack of competence;
• excess of regulatory power;
• conflict with statute;
• procedural defects;
• insufficient reasoning;
• breach of equality or competitive neutrality; and
• incompatibility with the Constitution.

Challenges may also be grounded on the breach of constitutional administrative principles, including efficiency, particularly where the measure leads to disproportionate costs, operational dysfunction or unjustified restrictions on competition or service delivery.

Although not part of the judiciary, courts of accounts may also play a role in disputes involving secondary legislation and administrative acts. This is especially true at the federal level, where the TCU has become one of the main forums for more intense challenges to subordinate rules in matters involving procurement, regulation and public expenditure. In practice, there is usually greater room for broader scrutiny of legality, economic rationality, efficiency and the substantive merits of administrative decisions before the TCU; although similar discussions may also arise before state courts of accounts, it is at the TCU that this type of review has been most consistently and visibly developed. Its findings may also influence or give rise to subsequent judicial challenges.

If the normative act is sufficiently autonomous and general, constitutional review may in some cases proceed through a direct constitutional action. Otherwise, the challenge is usually brought in ordinary proceedings or by writ of mandamus.

Challenges to individual decisions are one of the core functions of Brazilian public law litigation. This includes licensing decisions, sanctions, tax assessments, procurement exclusions, regulatory determinations, disciplinary measures, civil service decisions and refusals to grant benefits, permits or authorisations.

From a structural perspective, two distinct avenues of control may be engaged. Judicial review before the courts is the primary mechanism for protecting individual rights. It allows the affected party to seek annulment, modification or compensation in relation to an unlawful administrative act, with binding and enforceable outcomes in the specific case.

In parallel, courts of accounts may examine the same underlying administrative decision as part of their external control over legality, legitimacy and efficiency, particularly where public expenditure or procurement is involved. However, this form of review is not jurisdictional in nature and does not provide a direct remedy to the affected individual; its outcomes are typically directed at the administration and may lead to corrective measures, sanctions or recommendations, without substituting judicial protection.

The appropriate remedy depends on the circumstances. Where the claimant has a clear legal right supported by documentary evidence and seeks quick relief, a writ of mandamus is often used. Where the case requires a fuller evidentiary record, damages or broader declaratory relief, the claimant will usually proceed through an ordinary action.

Administrative contracts, concession agreements, public-private partnership arrangements and procurement-related instruments may all be challenged for illegality, lack of competence, procedural defects, deviation from public purpose, unequal treatment or breach of mandatory statutory requirements.

Even when the contract contains private law elements, courts will normally review whether the public entity complied with the constitutional principles that govern public administration and procurement. At the same time, Brazil allows arbitration in certain disputes involving disposable patrimonial rights of the public administration, but this does not eliminate judicial review of non-arbitrable issues, public law defects or the validity of the arbitral process itself.

As a rule, acts that produce legal effects are the clearest target for judicial review. Soft law instruments such as advice, guidance, technical notes or informal statements are less likely to be challenged on a standalone basis if they are merely advisory and do not alter anyone’s legal position.

That said, form is not decisive. If guidance effectively binds officials, determines market conduct, conditions participation in public procedures or creates an immediate and concrete threat to rights, courts may treat it as being reviewable. In practice, claimants often challenge either the first implementing act or the refusal of the administration to depart from the guidance.

A challenge is possible when the person or body is exercising public authority, performing a delegated public service or acting under a public law framework. Concessionaires, regulated service providers, public professional councils and state-owned entities can all become respondents to public law claims when the dispute concerns public powers, sanctions, access obligations, procurement, tariffs or other regulatory duties.

By contrast, purely commercial conduct is usually not reviewed through administrative law doctrines. A state-owned enterprise that buys and sells in the market without using public prerogatives will generally be treated under private law, subject to the ordinary rules of civil, commercial or labour litigation.

No complete ousting of judicial review is possible, as the Constitution guarantees that no injury or threat to a right may be removed from judicial scrutiny. Legislation may define procedural routes, standing rules, time limits and the allocation of jurisdiction, but it cannot fully exempt unlawful or unconstitutional state action from review.

Contractual clauses also have limited effect in this respect. Forum selection and arbitration agreements may govern disputes over arbitrable patrimonial issues, but they do not prevent the courts from reviewing non-arbitrable public law matters, granting urgent judicial protection where appropriate or policing the legality of the dispute resolution process.

In individual litigation, claimants normally must show a personal and legally relevant interest in the challenged act. Brazilian procedure does not require that the person be the only one affected, but there must usually be a direct connection between the act and the claimant’s legal sphere. The position is different in collective and constitutional litigation.

The Public Prosecutor’s Office, the Public Defender’s Office, public entities, class associations, trade unions, political parties and citizens may have standing under specific constitutional or statutory provisions even when they were not themselves directly affected in a personal sense. Standing therefore depends heavily on the remedy used.

Associations and NGOs may bring public civil actions or collective claims in areas such as environment, urban policy, consumer protection, cultural heritage, administrative probity and other diffuse or collective rights, even if they were not individually affected.

Courts usually look at the claimant’s institutional purpose, representativeness and, in some settings, minimum time in existence. Brazilian law is generally receptive to organised civil society participation in public law disputes, but the exact scope of standing still depends on the specific remedy and the right at issue.

Brazil permits joinder when the claims are connected by subject matter, legal basis or factual background, and when the same court and procedural route can hear them together. Multiple claimants may sue jointly, and multiple public or private respondents may be joined if the controversy is interdependent.

As a rule, joinder is initiated by the claimant in the initial pleading, by including all relevant parties as co-claimants or co-defendants. The court may also order the inclusion of necessary parties where their participation is required for the effectiveness of the judgment (necessary joinder). In such cases, the claimant may be instructed to amend the complaint to include the missing party, or the proceedings may be stayed until proper joinder is completed.

In addition, third parties with a legal interest may intervene on their own initiative or be called into proceedings by an existing party. The Civil Procedure Code provides several mechanisms for this, including voluntary intervention, joinder upon notice and third-party notice, each with specific procedural requirements and effects. In procurement and concession disputes, for example, the successful bidder or the contractual counterparty is often brought into the proceedings because the outcome may directly affect its position.

Additional parties may appear in several roles. They may act as co-claimants or co-defendants, as simple or litisconsortial assistants, or as amici curiae where the case has broader legal, regulatory or social relevance. The Public Prosecutor’s Office may also intervene in some cases to protect the legal order or collective interests.

In practice, the role depends on the effect of the judgment. A bidder whose award may be annulled, a concessionaire affected by a challenge to a regulatory decision, and an association representing a wider sector may all participate to defend their interests or to contribute technical and institutional context.

Brazil does not have automatic disclosure or discovery in the common law sense. Parties are expected to file the documents on which they rely, and the court may order the production of specific materials when necessary. In a writ of mandamus, the case must generally be supported by pre-constituted documentary evidence, so there is no discovery stage.

In ordinary public law cases, the administration may be required to produce the administrative record, internal documents or technical materials that are relevant to the dispute. Even then, the process remains judge-managed and targeted rather than open-ended.

The court has several tools to ensure it has access to relevant information. It may order a party or a third party to produce identified documents, request records from public authorities, appoint experts, seek technical clarifications and draw adverse procedural consequences from unjustified non-production. The duty of procedural co-operation under the Civil Procedure Code also applies.

Outside litigation, claimants often use freedom of information mechanisms and administrative file access rights to build the record before filing a suit. This is especially important in public law cases because the strength of the documentary record frequently determines the available remedy and the speed of judicial relief.

In ordinary proceedings, live testimony, expert evidence and hearings are available, and witnesses may be questioned under the judge’s supervision. This is more common where the dispute turns on technical facts, causation or contested events.

Many administrative law cases, however, are decided primarily on documents. A writ of mandamus is the clearest example: it is designed for clear legal rights that can be demonstrated without evidentiary expansion, so live evidence and cross-examination are generally not part of that procedure.

There is no general pre-action correspondence regime in Brazil comparable to that found in some common law jurisdictions. In many cases, a claimant may go directly to court once there is an actual or threatened violation of rights.

That said, preliminary steps are often strategically important. A prior administrative request may be needed to crystallise the authority’s position, obtain access to the file, identify the competent respondent or demonstrate urgency and good faith. Sector-specific rules may also create prior administrative stages, although these do not usually eliminate the constitutional right of access to the courts.

There is no universal requirement to exhaust internal administrative appeals before filing a judicial challenge. Because access to the courts is constitutionally protected, the general rule is that judicial review may be sought even if an internal appeal remains available.

Even so, exhaustion can apply in practice. Some disputes are better brought after the final administrative act, and some sectoral regimes or factual settings make prior administrative review useful or commercially necessary. Courts will also distinguish between a challenge to a completed decision and a complaint about mere procedural steps in an unfinished administrative process.

Time limits depend on the remedy. The best-known special period is the 120-day time limit for writ of mandamus, counted from official knowledge of the challenged act. Ordinary claims against public entities are generally subject to longer statutory limitation periods, often five years, although the exact rule depends on the type of claim.

Collective actions do not have a single uniform short deadline comparable to a writ of mandamus, and direct constitutional review does not follow the same logic as an individual challenge to an administrative act. In urgent matters, however, delay can undermine interim relief even where the underlying claim is still timely.

To start a claim, the claimant must ordinarily identify the parties, set out the relevant facts, state the legal grounds, specify the relief sought and file the supporting documents. It is also necessary to demonstrate standing, jurisdiction and, where applicable, urgency. Power of attorney and court-fee documents or exemption requests must also be provided.

The level of documentary support varies by remedy. In a writ of mandamus, the claimant must present a complete pre-constituted record showing the clear legal right and the existence of the challenged act. In an ordinary action, the initial evidentiary threshold may be lower because further proof can be developed during the case.

Legal arguments begin in the initial pleading and are answered in the defence. The claimant should present the core legal theory and the key documents at the outset, especially if urgent relief is sought. The defendant then files its response, often with the administrative record and legal justification for the challenged act.

After the pleadings, the judge defines the disputed issues and the evidentiary phase. Additional evidence, expert appointments and hearings come later if needed. In document-heavy public law disputes, many cases are resolved without a lengthy evidentiary stage because the record is already sufficient for judgment.

There is no separate permission stage equivalent to the leave requirement found in some judicial review systems. Once the claim is filed, the court checks ordinary admissibility criteria such as jurisdiction, standing, timeliness, procedural adequacy and documentary completeness. If those basic conditions are not met, the case may be summarily dismissed or the claimant may be ordered to cure the defect.

At the appellate level, however, Brazil does have important filtering mechanisms, especially for extraordinary review before the higher courts, where admissibility and precedent-based tests play a substantial role.

Urgent claims can be accelerated through interim measures, writ of mandamus and the general regime for provisional relief under the Civil Procedure Code. The claimant must usually show a strong likelihood of success and a risk of irreparable or serious harm, or a risk that the useful result of the case will be frustrated by delay.

Expedition is common in matters relating to procurement, sanctions, public service continuity, health, access to documents and regulatory disputes. Even so, relief against public entities may be affected by statutory restrictions and by the possibility of the government seeking suspension of an injunction on serious public order grounds.

The court’s primary task is to review legality, constitutionality and the rationality of the decision-making process, rather than to substitute its own policy preferences for those of the administration. Brazilian courts examine competence, procedure, stated reasons, factual support, consistency with statute and respect for constitutional principles. The intensity of review varies.

Courts are usually more deferential in matters involving complex policy choices or highly technical assessments, but they become more interventionist where there is a clear legal error, insufficient reasoning, disregard of evidence, disproportionate sanctions or an impact on fundamental rights. Review may therefore extend beyond pure procedure without becoming a general merits appeal.

In parallel, courts of accounts exercise external control over administrative action, with a strong focus on legality, economic efficiency and value for money. Their decisions may lead to the annulment or suspension of administrative acts, the imposition of sanctions on public officials, or orders to correct irregularities. While not exercising judicial review, their findings on inefficiency, waste or the mis-allocation of public resources may inform or trigger subsequent judicial scrutiny, especially in procurement and public contracting contexts.

Brazil has a written Constitution, and constitutional challenge is central to public law litigation. Administrative decisions, statutes, regulations and even judicial interpretations may be challenged on the basis that they conflict with constitutional rights, institutional competences or structural principles.

The Brazilian Constitution is notably detailed and wide-ranging, addressing not only core institutional arrangements and fundamental rights but also extensive aspects of economic regulation, public administration, taxation and social policy. As a result, a broad range of legal disputes may be framed in constitutional terms, making constitutional arguments a pervasive feature of litigation.

Such claims can be brought in concrete litigation or, where the Constitution so allows, through direct constitutional review before the Supreme Federal Court or a state constitutional court. Constitutional arguments are especially common in disputes involving:

• due process;
• equality;
• legal certainty;
• freedom of enterprise;
• federalism;
• property;
• access to justice; and
• separation of powers.

Procedural error is one of the most common grounds of challenge. Courts may annul or suspend a decision if the authority failed to observe mandatory procedural steps such as notice, hearing rights, reason-giving, consultation duties, competence rules, bidding formalities or the proper sequence of an administrative process. Brazilian courts will often ask whether the defect was material and whether it impaired defence rights or the integrity of the decision-making process. Not every minor irregularity leads to nullity, but defects that affect due process, transparency or equal treatment are taken seriously.

Courts may review whether the factual premises of the decision are supported by the record, whether the authority ignored decisive evidence or whether there was a manifest error in classification, calculation or causation. The room for intervention is greater when the mistake is objective and documentable.

In highly technical matters, courts tend to examine whether the administration had a reasonable evidentiary basis and adequate reasoning, rather than replacing expert judgement wholesale. Where the case is brought by a writ of mandamus, factual error must usually be demonstrable through documentary evidence alone.

A public authority may be challenged if it:

• unlawfully abdicates its discretion;
• treats internal guidance as inflexible law;
• acts under an impermissible external command; or
• refuses to exercise a power that the law requires it to consider.

Brazilian administrative law accepts that discretionary powers must be exercised by the competent authority for the proper public purpose. This ground often overlaps with deviation of power, insufficient reasoning and violation of legality. It is particularly relevant where regulators apply rigid internal criteria without engaging with the specific case or where an authority simply refuses to decide.

Bias and lack of impartiality can invalidate administrative action. This may arise from personal interest, conflict of interest, prior involvement incompatible with neutral adjudication or other circumstances that compromise the objective fairness of the process. In Brazil, the issue is often framed through the constitutional principles of impersonality, morality and due process. Depending on the context, the claimant may rely on general constitutional guarantees, specific recusal rules or administrative procedure statutes.

Unequal treatment is a well-established ground of challenge. Claimants frequently argue that a public authority treated comparable persons differently without an adequate legal basis, imposed inconsistent sanctions, changed criteria without justification or distorted the level playing field required in procurement and regulation. This ground is normally linked to equality, legality, impersonality, legitimate expectations and legal certainty. The key issue is usually whether the administration can justify the differentiation through objective reasons that are compatible with the governing legal framework.

Brazil is not a party to the European Convention on Human Rights, but it is a party to the American Convention on Human Rights and a wide range of other human rights treaties. Human rights arguments may therefore be brought through the Constitution itself and, where relevant, through treaty norms incorporated into domestic law.

Brazilian constitutional law gives some human rights treaties constitutional status when approved through a special legislative procedure, while others are generally treated as having supra-legal force. In practice, human rights reasoning is common in cases involving due process, equality, access to justice, health, vulnerable groups, detention, freedom of expression or socio-economic rights.       

Proportionality is an important review standard in Brazilian public law. It is particularly relevant in cases involving sanctions, police powers, restrictions on economic activity, disciplinary measures, procurement penalties, regulatory intervention and limitations on fundamental rights.

Courts often examine whether the measure was suitable, necessary and balanced in relation to its stated aim, although the terminology used may vary. Proportionality is also frequently analysed together with reasonableness, legal certainty and the duty to give proper reasons.

Additional grounds commonly invoked in Brazil include:

• lack of competence;
• improper purpose;
• misuse of procedure;
• insufficient or contradictory reasoning;
• violation of legal certainty;
• frustration of legitimate expectations;
• retroactive application of a new understanding;
• breach of good faith; and
• failure to consider the practical consequences of invalidation in the manner required by modern Brazilian public law.

In recent years, consequence-sensitive reasoning and the protection of settled situations have become increasingly visible, especially in disputes involving regulatory stability, administrative revision and long-term public contracts.

There are very few categories of decision that are entirely immune from challenge; even highly discretionary or politically sensitive acts may be reviewed for constitutional defects, lack of competence, procedural irregularity, manifest irrationality or misuse of power. That said, courts are often cautious when reviewing core political choices, legislative interna corporis matters, technical regulation or macro-budgetary policy. The practical limit usually relates to the intensity of review rather than absolute non-justiciability.

The defendant must normally explain its defence after service or notification, in the procedural form appropriate to the remedy used. In a writ of mandamus, the allegedly offending authority provides information to the court, and the public legal office of the relevant entity typically defends the act. In ordinary proceedings, the defendant files a defence and usually brings the administrative record.

Typical defences include:

• lack of standing;
• lack of jurisdiction;
• untimeliness;
• use of the wrong procedural vehicle;
• the absence of a clear legal right;
• the legality of the administrative act;
• administrative discretion;
• the separation of powers;
• public interest concerns;
• factual complexity incompatible with summary proceedings;
• res judicata; and
• the binding force of precedent.

Interim relief is widely available and is a crucial feature of Brazilian public law litigation. Claimants commonly seek:

• suspension of a sanction;
• stay of a tender decision;
• preservation of contractual equilibrium;
• continued participation in a procurement process;
• access to documents;
• reinstatement of a licence; or
• an order compelling the authority to decide.

The main forms are preliminary injunctions and other provisional measures under the Civil Procedure Code, as well as the traditional interim order in a writ of mandamus. However, relief against the public administration is affected by statutory restrictions in some contexts, and the government may seek the suspension of an injunction where it argues that the order seriously harms public order, health, security or the economy.

Damages are usually awarded through ordinary proceedings rather than through the narrower summary remedies used to set aside administrative actions. Brazilian law recognises state liability for unlawful acts and (in appropriate cases) omissions, subject to the relevant constitutional and statutory framework.

A claimant seeking damages must normally prove the unlawful conduct, the loss suffered and causation. In many public law disputes, the claimant combines a request for annulment or declaratory relief with a damages claim, although the court may separate the issues or require a fuller evidentiary phase.

In a concentrated constitutional review, the Supreme Federal Court may strike down federal or state legislation, and state courts may invalidate state or municipal norms under the relevant constitutional framework.

In concrete litigation, courts may refuse to apply a law they find unconstitutional in the case before them. The route and effects depend on the procedural vehicle used. A challenge based only on illegality, rather than unconstitutionality, will usually target secondary norms or administrative acts rather than the primary legislation itself.

In such cases, judicial courts may annul or suspend the effects of secondary legislation or administrative acts that are found to be unlawful, either generally (where the procedural framework allows) or in relation to the parties before the court. Interim relief may also be granted to prevent the application of a challenged norm pending final judgment.

Courts may order the administration to adopt a legally required course of action, such as deciding a pending application, granting access to information, reinstating a procedural position, providing a benefit where the legal entitlement is clear, or refraining from unlawful interference. Brazilian courts are more cautious when the requested order would require them to redesign public policy or make highly discretionary choices for the administration. The usual logic is that the judiciary may enforce a legal duty, but should avoid becoming the primary decision-maker on matters reserved to the executive.

If a decision is found unlawful, the court may annul it, suspend its effects, remit the matter to the administration for a fresh decision or, where the record is sufficient and the claimant’s right is clear, directly recognise the entitlement claimed. The next step therefore depends on the type of illegality and the remedy used.

In modern Brazilian public law, consequences matter, with courts paying increasing attention to the practical effects of invalidation on third parties, public services, regulatory stability and reliance interests. For that reason, the judgment may include directions about transition, the preservation of lawful effects or the way the administration must reprocess the matter.

Brazil has several mechanisms that mitigate excessive costs, although not in the same form as protective cost orders in some common law systems. Indigent claimants may obtain legal aid, which can cover court fees and other procedural costs. Collective and constitutional actions also contain cost-reducing features, particularly where the claimant acts in good faith to protect a public interest.

In addition, certain procedural avenues inherently limit cost exposure. In a writ of mandamus, for example, there is generally no award of attorneys’ fees, which reduces the financial risk for claimants seeking urgent protection of clear legal rights.

More broadly, the absence of broad discovery and the judge-led structure of proceedings usually make public law litigation less expensive than in systems built around extensive disclosure.

Brazil does not have a general and fully developed regime of public interest costs orders comparable to that seen in some common law jurisdictions. Even so, public interest litigation often benefits from special statutory cost rules. A citizen who brings a popular action in good faith is not exposed to costs and fees in the ordinary way, and public civil action legislation also reduces or postpones certain cost burdens for qualified claimants acting without bad faith. Courts retain room to address abusive litigation or bad faith, but they are generally aware that excessive cost exposure should not discourage the protection of diffuse and collective rights.

There is no exact equivalent to the English concept of wasted costs, but Brazilian procedure does contain functional substitutes. Courts may sanction bad-faith litigation, abusive procedural conduct and manifestly groundless incidents, and may allocate costs and penalties accordingly. In limited situations, legal representatives may also face personal consequences under procedural or professional rules. The structure is therefore less focused on a standalone wasted costs jurisdiction and more on bad faith, abuse of process and disciplinary accountability.

Judgments in challenges to government decisions are generally appealable. The available appeal depends on the procedural posture and on the type of judgment or interlocutory order involved. In an ordinary first-instance case, the main route is an appeal to the relevant appellate court. In some cases, interlocutory orders may be challenged immediately. After the appellate stage, further review may be possible before the Superior Court of Justice or the Supreme Federal Court if the case raises federal or constitutional questions and the statutory admissibility requirements are met.

Appeals from first-instance federal judgments usually go to the relevant Federal Regional Court, while appeals from first-instance state judgments usually go to the relevant State Court of Justice. Depending on the case, later review may proceed to the Superior Court of Justice on federal law issues and to the Supreme Federal Court on constitutional issues. Where the original decision was rendered by an appellate court in its original jurisdiction, the route depends on the specific remedy and the constitutional rules governing that court.

Permission is not usually required for an ordinary appeal from a first-instance judgment. The position is different for special and extraordinary appeals to the higher courts, which are subject to strict admissibility filters and are first examined by the court that rendered the appealed judgment. If that court refuses transmission, the party may use the procedural mechanisms available to challenge the refusal before the higher court. In constitutional litigation, additional route-specific admissibility rules may also apply.

The nature of the appeal depends on the appellate route. An ordinary appeal may involve review of both law and fact within the limits of the record and the issues properly raised. Interlocutory appeals are more focused on the specific procedural ruling under challenge. By contrast, appeals to the Superior Court of Justice and the Supreme Federal Court are not full rehearings. They are primarily designed to resolve federal or constitutional questions and do not ordinarily permit a fresh reassessment of the factual record.
