It is the prime responsibility of the establishment to get the establishment covered in time as and when the act is applicable under Section 1(3) or 2A, as the case may be. In case the establishment was coverable from December 2013 and you applied for registration or obtained a code in March 2014, you are liable for the imposition of interest and damages under Sections 7Q and 14B, which are detected later by the department, and an opportunity is given to hear you before such action.
However, if you applied for coverage in time but the allotment of your employer's code is delayed by the department, you can raise the issue before the competent authority, i.e., RPFC, where the damages part can be waived off subject to the favorable facts of your case.
