The disciplinary committee of the PCC held a marathon four-hour meeting here and served 100 leaders, including Aggarwal with show cause notices asking them to explain within ten days why they worked against the party's official nominees in different municipal corporations, PCC spokesman Dhirendra Pratap said.
PCC vice president Suryakant Dhasmana, who unsuccessfully contested for Dehradun mayoral seat losing it to BJP's Vinod Chamoli, had lodged a complaint against Aggarwal accusing him of campaigning against him.
