European Commission imposes interim measures for first time in nearly two decades

The European Commission (Commission) has the power to order companies suspected of engaging in anti-competitive behaviour to stop their conduct pending a final decision in an investigation – so-called “interim measures”. The idea is that interim measures prevent activity which could irreparably damage the market before the Commission has completed its probe and had a chance to sanction the behaviour. But these powers have rarely been used. In fact, they have lain dormant since the IMS Health case 18 years ago, where the Commission imposed interim measures ordering the firm to grant a licence in relation to pharmaceuticals data.

But these powers have rarely been used. In fact, the last time the Commission imposed interim measures was 18 years ago, against IMS Health, ordering it to grant a licence in relation to pharmaceuticals data.
