Scottish Labour leader, Richard Leonard, summoned the party’s council groups to a meeting yesterday – but there was no invitation for the Aberdeen’s elected members.
Aberdeen Labour’s nine councillors have been suspended from the party since forming an official alliance with the Conservatives in the wake of last year’s council elections.
A recent ruling by the powerful Scottish Executive Committee was to pass the decision south to UK Labour’s National Constitution Committee.
It is understood they will discuss the matter in early July.
But less formal ‘confidence and supply’ arrangements are in place with Conservative groups in other Scottish councils including North Lanarkshire and Falkirk.
They have escaped any disciplinary action.
The suspended members have won support from north-east Labour heavyweights like Dame Anne Begg and Lewis Macdonald MSP.
But with Jeremy Corbyn in charge of the UK party, it is thought that the chance of re-admittance is slim.
A senior Aberdeen Labour source said: “The irony of them passing it down to the UK party like this is that it is Scottish Labour acting like the branch office that it hates being called so much.
“The group is solid about remaining in the administration. We genuinely believe the SNP would ruin the city.
“They are looking at this from a first-past-the-post perspective. You need to form coalitions in councils because of the voting system.”
Scottish Labour did not respond to requests for comment.
