Kerala Home Minister Kodiyeri Balakrishnan on Thursday ordered a vigilance inquiry into the allegations against P.V. Sreenijin, son-in-law of the former Chief Justice of India K.G. Balakrishnan, that he acquired wealth disproportionate to the known sources of his income.

Earlier in the day, Additional Chief Secretary K. Jayakumar forwarded the case file to the Minister's office after eliciting legal opinion. Further action will be initiated by the Director of the Vigilance and Anti-Corruption Bureau.

Mr. Sreenijin, a former State vice-president of the Youth Congress, resigned from the organisation in the wake of the charges raised against him.

Chief Minister V.S. Achuthanandan had directed the Home Minister to look into the case on a private complaint.

The Income Tax Department also has started an inquiry into the charges. Department sources said the ambit of the probe and the course of action would be determined in due course.

Official sources said that once the allegations were established, action could be taken against Mr. Sreenijin under Sections 8 and 9 of the Prevention of Corruption Act.

These provisions say action can be taken for seeking gratification by corrupt or illegal means to influence a public servant.

Taking gratification for exercising personal influence with a public servant is also a punishable offence. For invoking such provisions, the accused need not be a public man, according to the sources.
