Daeth y llys i’r casgliad fod y cyn Brif Weinidog, wrth wneud penderfyniadau am y gweithdrefnau i’w dilyn gan yr ymchwiliad annibynnol, wedi gweithredu’n groes i’r hyn yr ymgymerwyd i’w wneud mewn datganiad i’r wasg ym mis Tachwedd 2017. Roedd y datganiad yn nodi y byddai’r trefniadau paratoadol ar gyfer yr ymchwiliad yn cael eu gwneud yn annibynnol ar ei swyddfa ef.
The court concluded that by taking decisions on the procedures to be followed by the independent investigation, the former First Minister acted contrary to undertakings, which had been set out in a press statement in November 2017. This had stated that the preparatory arrangements for the investigation would be made separately from his office.
