The Judicial Magistrate Court at Valliyoor on Tuesday issued a non-bailable warrant against Anti-Kudankulam Nuclear Power Project Struggle Committee member S. P. Udayakumar after he failed to appear before the court in a case filed against him in connection with the ongoing protest. Since the launch of agitation against the project by Dr. Udayakumar from Idinthakarai, the police had registered a few hundreds of cases against the leaders and articipants. The police also registered a case against Meera Udayakumar in March after she called on her husband at the protest venue defying prohibitory orders clamped under Section 144 of the Criminal Procedure Code. Subsequently, summonses were served on her and her husband recently, asking them to appear before the trial court at Valliyoor on Tuesday. Leader of the Opposition in the Kerala Assembly and former Chief Minister of Kerala V. S. Achuthanandan, who was on his way to Idinthakarai to address anti-nuclear power protesters, returned to Thiruvananthapuram on Tuesday after he was being stopped on the Tamil Nadu-Kerala border by police personnel from Kanyakumari district. Later, speaking to presspersons, Mr. Achuthanandan said he was not going there to create any untoward scene. He also expressed his disappointment that he could not meet Dr. Udayakumar.
