The bill directly prohibits covenants that the Commerce Commission's market study identified as limiting the availability of land or sites for grocery store development, and it does this by deeming such covenants to contravene existing provisions in sections 27 and 28 of the Commerce Act. The effect of this is to make such covenants or provisions unlawful and unenforceable. This improves on the general prohibition in section 28 of the Act by avoiding the need for complex analysis of the covenant's impact on competition in the relevant market. The covenants described by the bill would instead be presumed to be anti-competitive.
