Consent amendment with '0' sharing duration

Question

In a Pushed Authorization Request (PAR) for consent amendment:

• Is it possible to amend consent which already has a 0 sharing duration? or should the request be rejected?
• For how long is it permissible to amend such a consent?

Answer

Consents that have expired cannot be amended. As a consent with a 0 sharing duration is, in effect, immediately expired, hence any amendment is simply not possible.
