Topic: Billing client for work performed by an unpaid student-intern

Digest: A law firm may bill a client for work performed by a student-intern despite the fact that the law firm does not pay the intern, because the intern receives academic credit for the work, as long as (i) the internship program complies with applicable law, (ii) the educational institution does not object to the client charges, and (iii) the charge is not excessive.
