PF: Does the EC require fellows who defended their PhD just before the MSCA PF call deadline additional documents confirming the defence of a PhD degree?

This is explained on p. 8 of the MSCA PF 2022 Guide for applicants: Applicants who have successfully defended their doctoral thesis but who have not yet formally been awarded the doctoral degree will also be considered as postdoctoral researchers and will be considered eligible to apply. The successful defence must be unconditional (no further requirements/corrections that need to be addressed) and take place before the call deadline. Supporting documentation may be requested.
