Ar wahân, gofynnodd Mr Bowen CF am gyfres o newidiadau sylweddol i’r Protocol Gweithredol. Fel Cadeirydd yr Ymchwiliad, roedd hawl ganddo ef wneud hynny wrth reswm. Roedd y newidiadau arfaethedig yn mynd ymhell tu hwnt i’r cylch gwaith roeddwn i wedi’i roi i’r Ysgrifennydd Parhaol, ac felly eglurodd hithau yn glir wrth Mr Bowen CF nad oedd ganddi’r awdurdod i gytuno arnynt, ac y byddai’n rhaid iddi eu cyfeirio yn ôl ataf i fel y Prif Weinidog.
Mr Bowen QC requested a further series of significant changes to the Operational Protocol, which as Chair of the Investigation he was of course entitled to do. The proposed changes went well beyond the remit that I had given to the Permanent Secretary, and therefore she made clear to Mr Bowen QC that she did not have the authority to agree them, and would have to refer them back to me as First Minister.
