I can't decide between Turian or Asari.
Humans would work, but people don't really trust them. Salarians would come off as overly science, and not be personable to the jury. Hanar are jellyfish; while they are formal and could certainly be good lawyers, they are more mysterious, and everybody knows they are very radical in their certain beliefs, not to mention their personality quirks. An Elcor could certainly be a good lawyer, but facing laypeople they would be really boring. No one knows anything about the Drell, and the jury would probably treat them as outsiders.
