"A thief who steals, himself decides the investigating officer to nab the accused," Gujarat Congress chief Arjun Modhwadia said, reacting to the constitution of the commission.
"Instead of handing over the probe to a sitting judge of Supreme Court or lodging a complaint, a 'Save Modi Commission' has been constituted to cover-up the entire incident," he alleged.
Modhwadia said that when call details (photocopies of telephone bills) of Leader of Opposition in Rajya Sabha Arun Jaitley had been illegally accessed, the BJP did not allow Lok Sabha to function for three days.
Delhi Police had nabbed the person who accessed Jaitley's calls and his accomplices and put them behind bars.
"But, in this case, the woman's phone, her relatives' phone calls and suspended IAS officer Pradeep Sharma's phone conversations were tapped. Despite the serious allegation, no FIR has been lodged," he said.
"The contracts of state government were awarded to the woman and her family members illegally," he alleged.
Gujarat government had last week denied that it had any role in awarding contracts to a company owned by the brothers of the woman who was being "illegally" snooped upon by state police.
Under attack over alleged snooping on a woman by Gujarat police, Narendra Modi government last night appointed a two-member Commission of Inquiry headed by a retired woman judge of the Ahmedabad High Court.
