Legal analysis: If after signing the contract, the franchisee did not participate in technical study, did not accept site selection services and equipment and materials, and did not start business before, according to the provisions of laws and regulations, the franchisee has the right to unilaterally terminate the contract, and can sue in court for rights protection and refund the franchise fee according to the unilateral termination right.

Legal basis: Article 12 of the Regulations on the Administration of Commercial Franchise should stipulate in the franchise contract that after the franchise contract is concluded, the franchisee can unilaterally terminate the contract within a certain period of time. This clause is called the "cooling-off period" clause, which gives the franchisor the right to terminate unilaterally.
