After around 24 h thought - this is the sort of case that comes up.

at the very bottom:
"We feel vindicated that the GMC made these decisions after we referred him to them when the trust didn’t.”
and part of the back-story was that the employer [trust] was well aware it was a systems error - I think there was only one English speaker present at the time - and this came out very strongly in the third day of the GMC case which was by and large unreported by the media, [ Bad foreign doctor IS news ; completely crap hospital system like another Staffs is NOT news ]
Part of the oral testimony, was that when he asked for Phenol, the Asian nurse knew they didnt have any so gave him some Drano which for some reason had been stored in a drug cupboard. It was further shown in the unreported day, that the hospital management were aware that communications were weak.
and yes there was a later HSE prosecution - over the storage of the drano.
all in the public domain... I was having chemo in the same trust during all this ....
