Speaking following a meeting of the full convention on Friday, Cosla's vice-president George Purcell said: 'Cosla is an inclusive organisation and as a result of this inclusiveness we have decided to commission a report involving fully all member councils.
Many if not all of Scotland's councils are underfunded as a result of the current distribution system and the solution will not be about taking away from some councils.
'If our new report shows that there is a case the solution has to be in the form of new money coming fully from the Executive.'
A copy of the full motion follows.
Cosla will commission a case in respect of the constituent members of Cosla affected by mismatch.
It will be predicated on the fact that new resources will be required to resolve the situation in recognition of the fact that this is a problem created wholly by the Scottish Executive.
All the evidence available will be used to construct the case.
The matter will be flagged up at Cosla's meeting with Andy Kerr on 25th July both to inform him of how matters will be progressed and also to ensure that the minister has early notice and is in a position to respond.
Mechanisms will be put in place to ensure that this decision is progressed as speedily as possible and certainly within the timescales of the spending review.
