## Basis
- [Lei n.º 6.385/1976 (Planalto, in Portuguese)](https://www.planalto.gov.br/ccivil_03/leis/l6385.htm): art. 25 establishes that, unless there is an express mandate with a term not exceeding one year, the portfolio manager and the securities custodian may not exercise the voting rights pertaining to the shares under their management or custody.

## How it applies
Legislation prohibits the exercise of voting rights by a portfolio manager regarding shares under their management, unless there is an express mandate with a maximum validity of twelve months. This requirement aims to protect investors' interests, ensuring the manager has specific and temporary powers to make deliberative decisions. Without this instrument formalized within the legal time limit, the manager is legally barred from voting in meetings or related votes on the assets under custody or management.
