Why are so many of y'all having havers over a simple question which has a simple answer? A Latin passive participle, the 4th of the 4 principle parts of most verbs, is often used as an adjective, and is always given in the nominative singular masculine form and in the 2nd Declension form and is declined accordingly. A single judge who is a man would be a Judge emeritus, a woman would be a Judge emerita; two women Judges emeritae, two or more all men or a mixture of men and women, Judges emeriti. It's exacly the same as alumnus: you have one alumnus or alumna, two alumni or alumnae.
Jimthedog: Did you see the correct answer, or have you not got that far yet?
Incidentally, the above is not just an academic position -- I have actually seen a woman referred to as a something-or-other emerita. As to the propriety of mixing an English word with a Latin modifier and declining the Latin (at least as far as respects number and gender -- we don't pay attention to case), this is not infrequent. In fact, there is a word for it : macaronic.
