English to Polish Bus/Financial Insurance

I am looking for the Polish equivalent of the above phrase as used in the sentence: "non-vitiation clause under which the Insurance will not be vitiated or avoided as against any insured party as a result of any circumstances beyond the control of that insured party or any misrepresentation, non-disclosure, or breach of any policy term or condition, on the part of any other insured party or any agent of any insured party"
