It was reported in July 2021 that the advance notice provided by the consent procedure was used in the Scottish Parliament in 2021 to arrange for draft legislation to be modified so that the Queen, one of the largest landowners in Scotland, would become the only person in the country not required to facilitate the construction of pipelines to heat buildings using renewable energy. The Scottish government did not disclose the intervention of the Queen's lawyer when the energy minister added the exemption to the green energy bill,[31] key legislation to combat the climate emergency.[32] It is not known why the Queen's lawyer wanted the bill changed.[33] Since its creation in 1999 the Scottish Parliament has given the Queen advance notice of at least 67 parliamentary bills deemed to affect her. It is not known how many were consequently changed.[34] The Scottish Liberal Democrat leader Willie Rennie asked the Scottish government in a parliamentary question for a list of acts amended as a result of exchanges with the Queen's representatives; the Scottish government ultimately refused to answer the question, but confidential briefing notes were later disclosed which said that it was almost certain that some bills had been changed before introduction, but that as they had not been "amended" in parliamentary terms they would not have been included.[6][7]
