B. Around 2002, the Defendant Union entered into a contract for the implementation of the instant apartment reconstruction project with the Asia Industrial Development Co., Ltd. (hereinafter “Tai Industrial Development”), and the remaining Plaintiffs except the Plaintiff L entered into a supply contract with the Defendant’s members to purchase commercial buildings or apartment houses from the Asia Industrial Development from around 2003 to 2009, or from the Defendant Union’s association. The Plaintiff L was transferred from the Plaintiff’s member to the buyer’s status as to the above commercial buildings A-106.
