Counsel for the Defence is certainly the most famous Jeff Hawke story and is considered by many critics and fans to be Sydney Jordan's masterpiece and indeed a masterpiece of the SF strip in general. Here's an excellent example featuring Skipper Prossit, "the ablest woman-skipper of the spaceways" and some BEMs.
Counsel for the Defence is reprinted by Titan in Overlord and in Jeff Hawke's Cosmos V7 #2.
