evidence: BENGALURU: The Karnataka High Court on Wednesday permitted Deputy Chief Minister D K Shivakumar to withdraw his petition as well as the appeal filed by him questioning the sanction given by the previous BJP government to the Central Bureau of Investigation (CBI) to prosecute him for allegedly possessing assets disproportionate to his known source of income under the Prevention of Corruption Act, as the very sanction itself has been withdrawn by the Chief Minister Siddaramaiah led Congress government now.
