In Havens Realty Corp. v. Coleman, the U.S Supreme Court ruled that testers – individuals who pose as renters or purchasers to gather evidence of discriminatory housing practices – have standing to sue under the Fair Housing Act (FHA). The case involved a real estate firm accused of racial steering by directing black home seekers away from predominantly white buildings and vice versa. The court held that if a tester alleges they received false information about housing availability due to their race, it constitutes an actionable claim under FHA even if they had no intention of buying or renting property. Additionally, non-profit organizations can also sue for damages if such discrimination frustrates their mission and drains resources meant for other activities.

In the Havens Realty Corp. v. Coleman case, there was no formal dissenting opinion recorded from any of the justices involved in this decision. The Supreme Court ruled unanimously (9-0) in favor of Coleman and others, affirming that testers - individuals who pose as renters or buyers to gather evidence of discriminatory practices - have standing to sue under the Fair Housing Act for racial discrimination even if they do not intend to rent or buy a property. Therefore, it is impossible to provide a summary for a dissenting opinion on this particular case as none exists.
