Europe
Following the announcement of the CMDh decision to stop the pilot on splitting of MRP/DCPs in the CMDh press release of June 2019, the CMDh has agreed on a further update of the related guidance document to clarify in which exceptional cases the CMDh will continue to discuss a possible splitting of procedures.
In exceptional cases where a splitting is legally necessary, e.g. legally enforced splitting procedures requested by the European Commission in cases of company divestment in order to avoid competition issues, or triggering of Article 50 by a member state (e.g. Brexit), the CMDh reserves the right to accept these subject to CMDh endorsement. In case of invalid splitting requests, not fulfilling the conditions above, the RMS may decide on his own whether to refuse the splitting or to involve the CMDh.
