"When somebody who has served in the judicial system and then represents the human rights is found to have broken the law, I think it is extremely important that an example be set for the rest of the country, which is, the person should be equally dealt under the law," Irani said on the sidelines of a programme here.
West Bengal Chief Minister Mamata Banerjee has twice written to President Pranab Mukherjee asking him to take appropriate action against Justice Ganguly.
A Supreme Court committee of three judges had indicted Ganguly for his "unwelcome behaviour" and "conduct of sexual nature" towards the intern.
Ganguly has denied the charges and refused to comment on demands for his resignation from the WBHRC.
