Kuwait Court of Cassation principle number 3186

An appeal transfers the action to the Court of Appeal with its factual elements and legal evidence, only within the limits of what has been appealed. A new ground may be added while the original claim remains unchanged. An example concerning the nullity of a lease of shops concluded by a non-Kuwaiti, which does not preclude basing his appeal on unjust enrichment as a new ground for the claim for equivalent performance.
