| ||1. Damages if ground for avoidance known to the other party
This Article provides that a party which knew or ought to have known of a ground for avoidance is liable for damages to the other party. The right to damages arises irrespective of whether or not the contract has been avoided.
2. The measure of damages
Unlike the damages in case of non-performance under Chapter 7, Section 4, the damages contemplated by this Article are intended simply to put the other party in the position it would have been in if it had not concluded the contract.
Company A sells software to company B and could not have been unaware of B’s mistake as to its appropriateness for the use intended by B. Irrespective of whether or not B avoids the contract, A is liable to B for all the expenses incurred by B in training its personnel in the use of the software, but not for the loss suffered by B as a consequence of the impossibility to use the software for the intended purpose.
