The committee had summoned the commissioners of three municipal corporations who appeared before it today.
"They were asked to provide a list of properties sealed between December 23 to January 15," they said.
The direction was given as it has come to light that some properties were sealed by civic bodies "without any specific direction" from the Supreme Court-appointed monitoring committee that is overseeing the drive, they said.
The commissioners were also directed by the committee to devise a mechanism to stop alleged "blackmailing and extortion" in the name of sealing drive, sources said.
The next meeting of the committee is scheduled for Friday.
