The council has asked the government to prove beyond reasonable doubt that PFI meets best value criteria, before it will sanction any such schemes in Renfrewshire.
The decision follows a move by education committee vice convener Iain Hogg, who spelled out his opposition to the policy in a letter circulated to all Labour group members on the eve of a meeting to discuss the use of the PFI.
He wrote that 'privatising education' was morally indefensible and electorally unpopular, and it would be retrograde in the extreme for a Labour administration 'to sanction profiteering in a system which has been run as a non-profit making concern for over 100 years'.
Mr Hogg said: 'I do not think the executive has a hope in hell of meeting our caveat.' He added: 'PFI is a policy entertained only by the desperate. It's a Tory policy, and changing the name to public-private partnership from PFI is like changing the nsame Windscale to Sellafield. They are still the same.'
