Answer:
Compensatory damage
Step-by-step explanation:
Assuming That GSI is liable for breach of contract, The measure of damage is :
Compensatory damage : This is the compensation to be paid by the breaching party ( GSI ) to the Non-breaching party ( D and D ) for losses they incurred in purchasing the house and also fixing up the missing components in the house. and this is because GSI falsely reported that those systems where in place before D and D purchased the house.
To determine the amount of compensation the standard measure ( difference between value promised and value actually delivered by the breaching party ) will be applied.
