Section 6 R(2) provided : "For the removal of doubts, it is hereby declared that nothing contained in Sections 6 H to 6 R shall 'be deemed to affect the provision of any other law for the time being in force so far as that law provides for the settlement of industrial disputes, but the rights and liabilities of employers and workmen in so far as they relate to lay off and retrenchment shall be determined in accordance with the provisions of Sections 6 H to 6 Q." By virtue of section 6 R(2) the provisions of the U.P. , prima facie, apply in the matters of lay off and retrenchment, because under the Seventh Schedule to the Constitution 512 legislation in respect of "Trade Unions, Industrial and Labour Disputes" falls within Entry 22 of the Concurrent List and both the State and the Union are competent to legislate in respect of that field of legislation.
