[36][37][38][39] Some local businesses, particularly Lerwick pub and night club owners via the Shetland Licensed Trade Association, claimed that Mareel would negatively affect their profits and an anonymous State Aid complaint was submitted to the European Commission on 17 July 2008.
Shetland Arts countered these claims by providing evidence that Mareel would "generate activity and vitality into the night-time economy of Lerwick, to the benefit of all including the local hoteliers, publicans and restaurants".
Another source of concern was Mareel's business plan which detractors claim is unrealistic, particularly in terms of revenue raised from sales at the cafe bar.
The Shetland Islands Council's finance officials reported the business plan to be "robust" and "well researched", but that costings estimates were "light" and audience and income targets "challenging".
Due to a 9:9 split convener Sandy Cluness used his casting vote and is reported to have said "As far as I am concerned you can go ahead and build Mareel"[45] as he delivered his decision, to "cheers of delight and lengthy applause from the 40 or so supporters"[10] who were present in the council chambers.
"[46] West Mainland councillor Gary Robinson called into question the convener's handling of the vote stating "I think Sandy (the convenor) has won a battle, but the war isn’t over yet"[45] and that he and other opponents (including Alison Duncan who had 6 weeks previously expressed his desire to "place a bomb"[45] under Mareel and Jonathan Wills, a one time supporter of Mareel) would be considering their options in the coming weeks.
They conceived the project, Mirrie Dancers, which involved members of the community and Shetland Lace knitters in the process of making work which will become part of the permanent installation at Mareel.
