The Aam Aadmi Party, which formed the government in Delhi recently and is making waves across the nation in the run-up to the 2014 General Elections due to its tough stand against corruption, seems to have some house cleaning of its own to do.According to a report published in The Times of India on Tuesday, Delhi Law Minister Somnath Bharti tried to influence a witness and tamper with evidence in a case he had handled last year.The report says Bharti's track record as a successful lawyer involves an indictment for "tampering with evidence" by a Patiala House Court.The report quotes CBI Special Judge Poonam A Bamba who in August last year hauled up Bharti and his client Pawan Kumar - facing prosecution on corruption charges - after the CBI accused them of influencing a prosecution witness by speaking to him on the phone and discussing the case.The case relates to Pawan Kumar's prosecution by the CBI in three separate cases for his alleged acts of omission and commission while employed with the State Bank of Mysore since 2006.Reacting sharply to the news report, Bharti denied the charges. "Will expose the CBI and its nexus to the hilt, wait for sometime," tweeted the Law Minister.A few days ago, Bharti was in the eye of another storm when it emerged that Bharti had allegedly rebuked law secretary AS Yadav as the latter expressed his inability to convene a meeting of all Delhi court judges at the state secretariat. According to news reports, Yadav had told the minister that the judiciary is independent of the executive and only the Delhi high court can summon a meeting of judges.
