The Attorney General may bring an action on behalf of this State, counties, municipalities, townships and other political subdivisions organized under the authority of this State in Federal Court to recover damages provided for under any comparable provision of Federal law; provided, however, this shall not impair the authority of any such county, municipality, township or political subdivision to bring such action on its own behalf nor impair its authority to engage its own counsel in connection therewith.
