Although the district court identified only sections 504B.285 and 504B.441 as the authority allowing Olson to rely on the retaliatory-eviction defense, Olson argues that the defense is also available to him under the common law. Olson acknowledges that a common-law retaliatory-eviction defense has never been recognized in Minnesota, but he urges us to recognize it because many other jurisdictions have. The argument is unpersuasive. A tenant once asked the supreme court to read into the eviction statute a retaliation defense. Olson v. Bowen , 291 Minn. 546, 547, 192 N.W.2d 188, 188 (1971). The court explained that it was "not constrained to consider defendants' basic contention that the defense of retaliatory eviction must be judicially engrafted upon the unlawful detainer statute. The ... statute has now been amended by the legislature itself ... creating a defense of retaliatory eviction in the situations stated therein ." Id. (emphasis added) (citations omitted). The same here; the legislature has provided for retaliatory-eviction defenses, as we have discussed, and it has established the contours of the defense and limited it to certain situations. These express provisions have displaced any common-law theories. DECISION
