Introduction to TJ. Voto.
TJ. Voto. is a customized instance of ChatGPT designed specifically to emulate the role of a Brazilian appellate court judge (Desembargador) in drafting judicial opinions (relatórios e votos) for second-instance appeals and interlocutory decisions. Rooted in deep legal knowledge, particularly in Brazilian constitutional, civil, administrative, penal, consumer, tax, and social security law, TJ. Voto. assists in writing fully structured judicial votes following formal judicial guidelines and using a standardized, logical method (FIRAC). A typical use case involves a judge, law clerk, or attorney uploading the case file and procedural information, prompting TJ. Voto. to draft a comprehensive vote, fully reasoned and formatted as required by the Brazilian judiciary. The tool ensures verbosity, neutrality, and adherence to procedural norms, making it a vital support tool for the legal community. For instance, in a civil appeal involving a health plan denial, TJ. Voto. could generate the full opinion based on supplied arguments, addressing all preliminaries and issues on merit, structured per judicial best practices.
Main Functions of TJ. Voto.
Drafting Judicial Votes (Votos)
Example
A judge needs to draft a vote on an appeal against a lower court’s ruling on a consumer dispute involving overbilling by an energy provider.
Scenario
The judge uploads the case summary and the parties' arguments. TJ. Voto. organizes the vote using the FIRAC method, addresses all legal preliminaries, discusses the merit with citation of legal norms and jurisprudence provided by the user, and finalizes with a formal dispositive clause. The vote is returned in formal judicial language and court-compatible formatting.
Generating Judicial Summaries (Ementa and Acórdão)
Example
After drafting a vote that grants an appeal in a public servant’s retirement benefit dispute, the user requests an ementa and full acórdão for publication.
Scenario
TJ. Voto. summarizes the main legal issues, procedural path, and reasoning in an ementa, followed by a full acórdão text that mirrors the structure and style of official appellate court rulings.
Preliminary and Merit Legal Reasoning
Example
In an appeal where the appellant argues both lack of jurisdiction and violation of constitutional rights, the user asks for each preliminary issue and merit argument to be discussed separately.
Scenario
TJ. Voto. creates individual sections in the vote for each issue: one for procedural questions (e.g., incompetência absoluta), another for material rights (e.g., direito à saúde), ensuring that each claim is examined distinctly, as required by judicial best practices.
