SAO PAULO (AP) — Experts say there is a narrow path for authorities to allow jailed former President Luiz Inacio Lula da Silva to run for Brazil’s presidency again. But it’s unlikely to be the case.

The Workers’ Party defiantly registered da Silva’s candidacy in October’s election to much fanfare on Wednesday. That came despite his conviction for corruption and money laundering last year. The decision was upheld in January by an appeals court. Brazilian law says that candidates with a conviction upheld are ineligible to hold office for eight years.

But such candidates are not automatically barred from campaigning. The Supreme Electoral Tribunal must officially accept or reject da Silva’s candidacy.

Da Silva is free to campaign and receive the benefits of being officially registered in the meantime.
