Minimum wages and related wage claims are barred where the Code's claim, direction, adjudication, or recoverability applies. No court shall entertain suits for recovery of minimum wages, deductions, wage discrimination or bonus payments insofar as the sum claimed (a) forms the subject of claims under section 45, (b) has formed the subject of a direction under this Code, (c) has been adjudged in any proceeding under this Code, or (d) could have been recovered under this Code.
