By “Hospital licence does not allow a full section” you presumably mean the hospital’s CQC registration? I may be able to help on that issue but email me at work, mat.kinton@cqc.org.uk. CQC’s advice for many years has been that general hospitals who occasionally use the MHA should add such use to their registration. It has also taken the position that it will respond proportionally to any hospital using the MHA prior to getting appropriate registration, where this is to avoid patient harm. So it may be that the situation you describe just shouldn’t happen and the initial s2 application should have been accepted: the general hospital may be being too cautious in declining to be the detaining authority. But happy to discuss and look at the specifics here offline. What I say here is in a personal capacity.
