It follows comments from the committee chairman Kevin Duffy
The association representing middle ranking gardaí says it will not engage with the Public Service Pay Commission.
It follows comments by the chair of the commission yesterday, when he said the threatened garda strike was tantamount to "mutiny".
Kevin Duffy was appointed by Government to chair the Public Service Pay Commission.
The former head of the Labour Court told an industrial relations conference yesterday that the now averted strikes by gardaí was best described with the word "mutiny".
Immediately the Garda Representative Association (GRA), which represents rank and file gardaí, said they had no confidence in Mr Duffy as chair of the commission.
And today the Association of Garda Sergeants and Inspectors (AGSI) has said it will not engage with the commission until at least their December meeting - which will decide if they have confidence in Mr Duffy.
