Presiding Officer Tricia Marwick said the Scottish government's treatment of a Labour MSP over questions he submitted was "not in my view acceptable", on 4 December 2012.
Ms Marwick was responding to a point of order from Labour MSP Mark Griffin.
Mr Griffin said he had written to the government asking three questions about its attendance and activity at the 2012 Ryder Cup.
He said after receiving a holding reply on 2 November 2012, it was not until 27 November 2012 when he recieived a reply merely referring him to an inspired question from SNP MSP Clare Adamson which was general and asked many weeks after his.
The Labour MSP said this was "disrespectful" and said the government should no use a "planted question to undermine opposition parties".
The presiding officer said after an investigation she felt this was a good and important point of order and to make a member wait nearly eight weeks for an answer, simply referring to an inspired question was in her view simply not acceptable.
Ms Marwick said she expected the Scottish government to "treat all members equally irrespective of which party they are from", saying the government had treated Mr Griffin with discourtesy.
