Instead of requiring an assessment of whether the covenant substantially lessens competition in the relevant market, the test in the new section 28A is intended to be relatively straightforward. Is the covenant or other provision one in which a designated grocery retailer has an interest; if so, does it have the purpose, effect, or likely effect of impeding someone else from operating a store in competition with that designated grocery retailer? The hope is that parties interested in acquiring or operating on a site will be able to answer those questions without the assistance of the courts. If legal disputes arise, they ought, at least, to be more factually straightforward than a case under section 27 or 28 of the Act.
