Weng, accompanied by some 40 red shirts, lodged his statement at the high court.
“The seven judges had acted in violation of the Constitution and should assume responsibility by resigning,” he said.
He said before the seven judges stepped down, they should cancel the court order as an act of remorse.
The seven are high court president Wasan Soypisudh and six judges, Jaran Pukditanakul, Charoon Intachan, Chalermpon Ake-uru, Nurak Marpraneet, Boonsong Kulbupar and Suphot Kaimuk. They are also being targetted by the red shirts for impeachment.
The two remaining judges, Chut Chonlavorn and Udomsak Nitimontree, are the dissenting voices opposing the judicial intervention.
Meanwhile, Pheu Thai MP Kokaew Pikulthong urged the Constitution Court to cancel its injunction on the legislative vote for charter change in exchange for avoiding impeachment and budget cut.
“The red shirts will stop the impeachment drive against the judges if the court order on legislative voting is dropped,” he said.
Kokaew also hinted that the House committee vetting the 2013 Budget Bill might cut the high court’s non-esstential expenditures, such as the spendings on security services for the court buildings and personnel.
