Minimum wages procedure requires committees or public proposals with defined composition, consultation and periodic review. The appropriate Government shall either appoint enquiry committees or publish proposals by notification for fixing or revising minimum wages; committees must have employer and equal employee representation with independent members not exceeding one third; notifications must allow at least two months for representations and require Advisory Board consultation when revisions follow the notification route; after considering recommendations or representations the Government shall notify rates, which ordinarily come into force three months after issue, and shall review or revise rates at intervals not exceeding five years.
