Right To Rent is to be challenged in the High Court just before Christmas.
The Joint Council for the Welfare of Immigrants says the hearing will take place on December 18 and 19.
The charity said: “This is going to be the first proper chance a court in the UK will have to determine the legality of the hostile environment Theresa May created that conscripted ordinary people into acting as her border guards.
“We are close to ending this pernicious experiment once and for all.”
Under Right to Rent, letting agents and landlords must check that all prospective tenants have a right to live in this country. Breaches can earn both civil penalties and criminal sanctions.
Opponents say that the scheme has led to discrimination and that a number of British-born tenants have no passports or driving licences and lack the documentation to prove they have a right to live here.
