But inserting a stipulation or proviso within optional time based on non-transfer of the sale object, and the condition of the effect of the dissolution of original contract in the related contract, lack of respecting the good faith principles in subsequent transactions, as well as the conclusion of authorized or optional transactions are from the cases that the liquidation tools extend to the past.
