GRP Rainer Lawyers and Tax Advisors in Cologne, Berlin, Bonn, Bremen, Dusseldorf, Essen, Frankfurt, Hamburg, Hanover, Munich, Nuremberg, Stuttgart and London www.grprainer.com/en conclude: In its judgment of March 27, 2013 (Az.: 25 U 59/12), the Berlin Court of Appeal ruled that a lessor potentially renders itself liable to pay damages to a lessee if it does not point out to the latter the requirement to give notice of defects to the supplier where there are assigned warranty claims for defects. In the event that liability pertaining to the lease agreement, which is not a commercial transaction from the perspective of the lessee, is excluded therein for the lessor and the lessee is referred to the enforcement of warranty claims in sales law vis-à-vis the supplier, the lessor has to make sure that the requirement to give notice of defects to the supplier is excluded. Otherwise, it must at least give the lessee effective notice of this requirement.
