MUMBAI, Aug. 22 -- The Bombay High Court on Thursday allowed Turkish ground handling firm Celebi Aviation's subsidiary to withdraw its petition challenging the revocation of its security clearance in May, which led to the termination of its contract at the Chhatrapati Shivaji Maharaj International Airport (CSMIA). A division bench of justices BP Colabawalla and Firdosh Pooniwalla disposed of the plea after senior advocate Chetan Kapadia, representing Celebi, sought to withdraw it. The Bureau of Civil Aviation Security (BCAS) had revoked the security clearance for Celebi Airport Services India Pvt Ltd on May 15, citing "national security" concerns. The decision was taken amid mounting tensions between India and Turkey over the latter's diplomatic and arms support to Pakistan during the four-day military clash with India post the Pahalgam terror attack in April. CSMIA was among several airports that terminated their agreements with Celebi after its security clearance was revoked. The company then filed three separate lawsuits, two of which challenged Mumbai International Airport Limited's (MIAL's) decision to terminate its contract at CSMIA. It also sought to restrain MIAL from selecting a new ground handling agency, for which tenders were issued on May 17. The third plea was filed against BCAS, stating that the civil aviation security regulator's move to revoke its security clearance was "arbitrary and illegal". Merely citing national security, without specific justification, was "vague" and "unsustainable in law," the petition said. However, the Bombay High Court had been deferring the hearing of the petition, awaiting the verdict on a similar plea in the Delhi High Court, which was eventually dismissed last month. A single-judge bench of justice Sachin Datta ruled that the Centre had taken the decision based on compelling national security and geopolitical considerations....
