Line of business restrictions as a solution to competition concerns


 8 June 2020  Paris  

Line of business restrictions are restrictions that limit the kind of activities that the operator of a facility can undertake. These restrictions can be structural in the sense that they prohibit a firm from engaging in a line of business, as set out in the OECD Recommendation on Structural Separation. Alternatively, they can be behavioural, for example restricting a firm’s scope to discriminate between those that one of its lines of business sells to, or restricting the firm’s ability to organise its lines of business, for instance by mandatory functional or legal (accounting) separation.

In June 2020, Working Party 2 will explore how effective different types of restriction have been in the utility industries in which they were often applied, and seek to understand whether similar issues arise in relation to self-preferencing by digital platforms.
