Roman Giertych submitted the complaint on Thursday, pointing to what he described as serious procedural violations and manipulation during the election.
Giertych alleged that vote counts were falsified, some polling stations were improperly staffed, and an unauthorised digital tool was used to block legitimate voters.
His challenge comes amid broader claims of errors in election reports and votes being incorrectly assigned to candidates.
The Supreme Court, which is reviewing election complaints, has already ordered a recount in 13 polling stations across Poland.
It said the goal is to determine whether errors were clerical or deliberate - and whether they could have affected the outcome of the June 1 vote.
According to a report by private broadcaster TVN24, the court has now received 192 election appeals.
The deadline for filing is June 16. A final ruling on the validity of the election must be issued by July 2.
The court’s Extraordinary Review and Public Affairs Chamber—a panel established by the previous government in 2018—is responsible for handling election disputes.
However, the chamber's legitimacy has been questioned by European courts and is contested by Poland's current ruling coalition.
The Court of Justice of the European Union has previously ruled that the chamber "does not have the status of an independent and impartial tribunal."
