Black's Law Dictionary
Henry Campbell Black, M.A. · 1910
Where a witness objects to a question propounded (particularly on the taking of a deposition) and states his reason for objecting or refusing to answer, it is called a "demurrer to the interrogatory," though the term cannot here be understood as used in its technical sense.
