http://proethica.org/ontology/case/179#Engineer_A_Multi-Party_Litigation_Expert
Definition

Engineer A was retained across three separate, unrelated litigation matters — twice by ABC Manufacturing (patent litigation) and once by Attorney X representing a plaintiff against ABC Manufacturing (product liability). During cross-examination, opposing counsel questioned whether these multiple engagements on both sides of litigation with the same company constituted improper conduct, raising issues of professional independence and objectivity.
