A probe by such a Commission is considered more credible than a normal police probe, sources said.
The illegal surveillance on the woman architect, allegedly by the Gujarat Police was apparently in violation of phone-tapping rules as it was reportedly carried out without the mandatory permission from the Centre when she went out of the state.
Sources said a state Home Secretary is empowered to order phone-tapping within the state but when the surveillance is carried out in multiple states, permission of the Union Home Secretary is mandatory.
The Gujarat Police appear to have tapped the telephone of the woman when she was also in Maharashtra and Karnataka, besides Gujarat, without taking any authorisation from the Union Home Secretary, the sources said.
