The Green Brigade have claimed representatives were turned away from a scheduled meeting with Celtic chief Michael Nicholson.
In the latest North Curve Celtic newsletter it is stated that members of the group were set to meet with the Parkhead chief executive to discuss The Celtic End and "other matters".
However, the meeting - scheduled for October 3 - did not take place with the group stating reps were turned away from Celtic Park as "one person was not to Michael's liking".

The group has the reason for the issue is down to one representative's "relationship with Palestine" branding the development as "cynical and uncomfortable".
Celtic officials previously sent a letter to the Green Brigade group branding a pro-Palestine display as "unacceptable" and citing incidents in away matches as members of the group were banned for a period.
The club stated the banning order - which has since been resolved - was "not imposed as a result of Palestinian flags".
However, the group have blasted the club over the recent meeting issue with a formal response yet to be received from the club.

"We remain eager to discuss the idea with the club, to have the opportunity to explore all and any other options and above all conduct a full and proper fan consultation," an update read.
"Although the club appears intransigent we will continue to promote The Celtic End where we can.
"The Green Brigade had a meeting scheduled with Michael Nicholson on 03/10/24 with a view to discussing The Celtic End and other matters outstanding from last season.
"Disappointingly, the GB reps were turned away from Celtic Park as one person was not to Michael's liking. The person in question has a longstanding relationship with the club however it is their relationship with Palestine which seems to be the issue now.
"This is a cynical and uncomfortable development which the GB is awaiting a formal response on."
