For example, a landscaping company mandated by the landowner signs a contract in which it agrees to ”keep the owner of the land and the railway company unharmed” for injuries that occur on the construction site. However, the insurance policy of the landscape company contains contractual provisions on liability that exclude these commitments for the insured and that cancel the ”damage management agreement”. The police restore liability to the owner of the land and the railway company, as would be the case if no contract with the landscaping company were concluded. An ancillary provision invalidates the contractual liability clause and reinforces the ”no damages” provision. .
