410.This section relates to subsections 1(2)(a)-(d) and 1(3)(a)-(c) of section 183. It provides that, for agreements involving price-fixing, limitation of production and market-sharing, undertakings must be operating at the same level in the chain of supply or production. The criminal offence does not apply to so-called vertical agreements, which relate to intended activity where the two or more parties are operating at different levels in the chain of supply or production (e.g. as producer and distributor or as distributor and retailer).
