Pita, the 42-year-old leader of the progressive Move Forward party whose election victory stunned Thailand's military-backed establishment, has faced multiple complaints from rivals, three of which the poll body has dismissed for late submission, while four others against the party have been thrown out.
Pita has downplayed the issue, arguing the shares in the firm, ITV, have since been transferred and the company was not an active media organisation.
"There is sufficient information to suspect that the candidate is unfit or prohibited from seeking public office, according to electoral regulations, to further investigate Pita," election commission chairman Ittiporn Boonprakong told Reuters in a text message.
"The election commission may take action against Pita in the future," he told a press conference.
