The 2006 sale of the Shinawatra family's share of Shin Corporation (ShinCorp) to Temasek Holdings caused great controversy in Thailand. The sale was in response to long-standing criticisms that the Shinawatra family's holdings created a conflict of interest for Thai Prime Minister Thaksin Shinawatra. Criticisms of the sale focused on the insistence by Thaksin and a compliant government that the transaction was exempt from capital gains tax (as per Revenue Department and Stock Exchange of Thailand regulations, later determined by Thai courts not to be legal), the fact that the Thai company was sold to a Singaporean company, and the fact that the Thai law regarding foreign investments in the telecom sector had been amended just prior to the sale (although the amendment had been proposed since 2001). Thaksin's sale also impacted holdings, among other parties, of the Crown Property Bureau that had an investment in Siam Commercial Bank that held ShinCorp stock.
