in a parliamentary ombudsman investigation released in may 2013, maija saxlin said that museum director janne gallen-kallela-sirén was biased in his position on the guggenheim helsinki plan. according to carl gustaf ehrnrooth, major owner of construction companies (including yit and pöyry), gallen-kallela-sirén made the proposal for the guggenheim museum; he was a board member of a company majority-owned by c–g ehrnrooth, and his wife also worked for the company. when tax havens were criticised and casimir ehrnrooth's accounts made public, helsinki politicians accepted a tax-haven-funded project. the 2007 finnish campaign finance scandal bribery sentences were overturned in the helsinki court of appeals in late june 2013.
