OPINION, judgment. A collection of reasons delivered by a judge for giving the judgment he is about to pronounce the judgment itself is sometimes called an opinion. 2. Such an opinion ought to be a perfect syllogism, the major of which should be the law; the minor, the fact to be decided and the consequence, the judgment which declares that to be conformable or contrary to law. 3. Opinions are judicial or extra-judicial; a judicial opinion is one which is given on a matter which is legally brought before the judge for his decision; an extra-judicial opinion, is one which although given in court, is not necessary to the judgment. Vaughan, 382; 1 Hale's Hist. 141; and whether given in or out of court, is no more than the prolatum of him who gives it, and has no legal efficacy. 4 Penn. St. R. 28. Vide Reason.
