Punjab government has refused to pay a bill of Rs 6.35 crore to the Center for deployment of paramilitary forces during and after the terror attack at Pathankot air force base.
In a communication to the Center, the state government has said that the deployment of these units was in "national interest" and "expenditure thereon should not be billed to the state government", officials said here.
NDA constituents Shiromani Akali Dal and BJP are in power in Punjab.
Whenever central paramilitary forces are provided to any state, their expenses are borne by the central government but it is adjusted against the state's budget later on, a home ministry official said in Delhi.
