Beat me to it, too.
I had a look on Findlaw but without more details I couldn't say what it is.
If it's a civil rights case you might mean:
Adams v. Richardson, 480 F.2d 1159 (D.C. Cir. 1973) ?
(upholding action against HEW under APA for failure to enforce antidiscrimination provisions of Title VI).
That case seems quite popular to cite. On Findlaw.
Kddani would have to help you from then on, as the Lexis sections our site licence gives access to wouldn't carry it.
