The ruling People Power Party(PPP) has filed for the Constitutional Court's adjudication on jurisdiction disputes over the opposition-led hearing on a public petition calling for a motion to impeach President Yoon Suk Yeol.

This comes after the main opposition Democratic Party(DP) unilaterally approved a hearing schedule and request for witnesses at the Legislation and Judiciary Committee on Tuesday.

In a press release on Friday, the PPP accused the DP of infringing upon its committee members' rights to represent the public, and to review and vote on motions, claiming there were a gross violation of the Constitution and illegalities in the process.

The PPP also requested the court to declare the committee passage of the hearing, scheduled to be held on July 19 and on 26 as null and void, and to accept an injunction to suspend its efficacy.

At a party meeting on Friday, PPP floor leader Choo Kyung-ho urged the DP to halt aggressive politics that violate the Constitution and destroy constitutionalism.
