(1) A collective agreement is legally enforceable on a certified trade union and an employer that have entered into it and on an employee who is a member of the recognized trade union, or member of a bargaining unit for whom that trade union has been recognized if the collective agreement—
(a) is in writing;
(b) provides that the parties intend it to be a legally enforceable contract in its entirety.
(2) Where a collective agreement which is in writing contains a provision stating that the parties intend one or more parts, but not the whole of the collective agreement as a legally enforcement contract, then—
(a) the specified part or parts shall be legally enforceable; and
(b) the remainder of the collective agreement shall not be legally enforceable,
and the part or parts of the collective agreement which are legally enforceable shall be incorporated into the contract between the employer and employee.
(3) Any party to a binding collective agreement may apply to the Tribunal to enforce the collective agreement.
