What actions could be contemplated against buildings constructed in violation of rules?

When buildings are constructed without obtaining necessary official plan approval from the concerned Municipal authorities or buildings are constructed in violation of the directions and the rules made there under, the officer of the taxing department may assess the tax liability and levy penalty twice the assessed amount.  Further, till the buildings constructed in violation of rules are not set-right, imposition of penalty continues. This action will not prohibit the law to take action against the unauthorized buildings.
