Ruling 2181

If the thing that one acquires from a settlement is defective, one can annul the settlement. However, if he wishes to take the difference between the price of a non-defective and defective item, it is problematic (maḥall al‑ishkāl) [i.e. based on obligatory precaution he cannot do so].2
2 As mentioned in Ruling 6, the term ‘problematic’ (maḥall al‑ishkāl) amounts to saying that the ruling is based on obligatory precaution.
