A researcher who had been added as a secondment host in a MSCA PF application didn’t give their permission beforehand and don’t want to participate. It there a way to report such cases?

Unfortunately, REA cannot intervene to alter a submitted proposal after the call deadline. However, if after the evaluation the proposal reaches the funding threshold, the beneficiary can further discuss to clarify the secondment issue during the Grant preparation (GAP) with the Project Officer assigned to the proposal.
