Kerala Chief Minister Pinarayi Vijayan on Monday alleged that the central agencies probing the gold smuggling case were exceeding their jurisdiction to malign and destabilise a constitutionally elected government. The state government, he said, would make necessary interventions within the existing legal framework. "It is a violation of their own jurisdiction and thereby an encroachment on the Constitution. This is undemocratic and unconstitutional and cannot be allowed. The state government will make the necessary interventions within the existing legal framework," he said.
