When you look at contracts for business acquisitions, you might see that some are subject to a condition of clearance or authorisation. You should know that section 51 of the Commerce Act 1986 used to talk about this. This section was repealed on 1 January 1991 by section 18 of the Commerce Amendment Act 1990, which you can find on the legislation website.

The repeal of section 51 means it is no longer part of the Commerce Act 1986. You can still find information about the repeal in the notes for section 51. The Commerce Amendment Act 1990 made this change to the law.
