Canon LIX.  (Greek lxiii.)

That clerics be not compelled to give testimony in public concerning the cognizance of their own judgment.

It should be petitioned also that they deign to decree, that if perchance any shall have been willing to plead their cause in any church according to the Apostolic law imposed upon the Churches, and it happens that the decision of the clergy does not satisfy one of the parties, it be not lawful to summon that clergyman who had been cognitor or present,⁴⁵⁹⁴⁵⁹    This must mean “who had heard the cause or been present at the hearing,” and so the Greek has it. into judgment as a witness, and that no person attached to any ecclesiastic be compelled to give testimony.

Notes.

Ancient Epitome of Canon LIX.

“According to the Apostolic law,” viz., that of St. Paul, 1 Cor. vi. 1, 2, etc.  I follow the Greek scholia in rendering this canon.  In Latin cognitor is he that is solicitor, or advocate, rather than the judge who takes cognizance.
