Task: songer_casetyp1_2-2

What follows is an opinion from a United States Court of Appeals.
Your task is to identify the issue in the case, that is, the social and/or political context of the litigation in which more purely legal issues are argued. Put somewhat differently, this field identifies the nature of the conflict between the litigants. The focus here is on the subject matter of the controversy rather than its legal basis.
Your task is to determine the specific issue in the case within the broad category of "civil rights". 

PER CURIAM:
Appellants, a group of District of Columbia residents representing the class of homeowners whose property is burdened by racial covenants, instituted this suit to enjoin the Recorder of Deeds from accepting such covenants for filing in the future and to require the Recorder to affix a sticker on each existing liber volume stating that restrictive covenants found therein are null and void. They also asked for an injunction preventing the Recorder from providing copies of instruments on file unless a similar notice is attached to the copies. The District Court dismissed their complaint, 330 F.Supp. 447 (1971), and a three-judge panel of this court affirmed that judgment. On reconsideration en banc of the judgment of the District Court we now reverse.
Reversed and remanded.
