A validly registered collective bargaining agreement under the Labour Act creates binding contractual obligations that cannot be unilaterally rejected or amended by oversight bodies such as the Local Government Board. Once a CBA is registered and published as a statutory instrument, it becomes effective and binding pursuant to section 80 of the Labour Act. The Minister has specific statutory powers under sections 79 and 81 to reject or amend collective bargaining agreements on grounds of inconsistency, public interest, unreasonableness or unfairness, but failure to exercise these powers leaves the agreement valid and enforceable. Courts must uphold the sanctity of contract and cannot rewrite contracts or excuse parties from the consequences of contracts freely and voluntarily entered into, even if terms prove onerous. The Local Government Board is an autonomous statutory body established under section 116 of the Urban Councils Act with independent legal personality, separate from the Minister and Ministry, and can only act through its properly constituted members.
