Is it permissible for the buyer to request the rescission of a commercial establishment sale contract and compensation for prior debts if the contract explicitly stipulates his assumption of those debts, and he undertook actions confirming his knowledge of them and acceptance of them?

It is not permissible for the buyer to request the rescission of a commercial establishment sale contract or compensation for prior debts if the contract explicitly stipulates his assumption of those debts, and his knowledge of them and acceptance of them were confirmed through his actions subsequent to the conclusion of the contract, such as his request to transfer the liabilities to his financial responsibility or his ratification of them.
