BOSTON — An opponent of Boston’s 2024 Olympics bid has taken a first step toward putting a question before voters on next year’s ballot.

United Independent Party Chairman Evan Falchuk said Thursday that he’s filed paperwork with the state’s Office of Campaign and Political Finance to form the “People’s Vote Olympics Committee.”

The failed 2014 gubernatorial candidate said key questions remain about Boston’s pursuit of the games.

Gov. Charlie Baker said Thursday that if people want to pursue a ballot question, “more power to them.”

Falchuk hasn’t detailed the language for a proposed ballot question, but said the goal is to give Massachusetts voters the chance to decide in a binding referendum whether Boston should host the 2024 Olympics.

Critics of Boston’s bid argue taxpayers will end up footing a costly bill.
