Comparative-Impairment Test Law and Legal Definition

Comparative-Impairment Test is a test applied when there is conflict of laws. This test asks which jurisdiction's interest or policies would be most impaired if its policies/laws were not applied in the case.

The following is an example of a case law referring to the term:

A "governmental interest" test is to be used to determine whether a genuine conflict between state laws exists. If so, then a "comparative impairment" test is used to determine which state has a greater interest in having its law applied. [Vestrock Partners v. California Energy Co., 1993 U.S. Dist. LEXIS 11882 (D.N.Y. 1993)].
