FIFTH ARTICLE [II-II, Q. 60, Art. 5]

Whether We Should Always Judge According to the Written Law?

Objection 1: It would seem that we ought not always to judge

according to the written law. For we ought always to avoid judging

unjustly. But written laws sometimes contain injustice, according to

Isa. 10:1, "Woe to them that make wicked laws, and when they write,

write injustice." Therefore we ought not always to judge according to

the written law.

Obj. 2: Further, judgment has to be formed about individual

happenings. But no written law can cover each and every individual

happening, as the Philosopher declares (Ethic. v, 10). Therefore it

seems that we are not always bound to judge according to the written

law.

Obj. 3: Further, a law is written in order that the lawgiver's

intention may be made clear. But it happens sometimes that even if

the lawgiver himself were present he would judge otherwise. Therefore

we ought not always to judge according to the written law.

_On the contrary,_ Augustine says (De Vera Relig. xxxi): "In these

earthly laws, though men judge about them when they are making them,

when once they are established and passed, the judges may judge no

longer of them, but according to them."

_I answer that,_ As stated above (A. 1), judgment is nothing else but

a decision or determination of what is just. Now a thing becomes just

in two ways: first by the very nature of the case, and this is called

"natural right," secondly by some agreement between men, and this is

called "positive right," as stated above (Q. 57, A. 2). Now laws are

written for the purpose of manifesting both these rights, but in

different ways. For the written law does indeed contain natural

right, but it does not establish it, for the latter derives its

force, not from the law but from nature: whereas the written law both

contains positive right, and establishes it by giving it force of

authority.

Hence it is necessary to judge according to the written law, else

judgment would fall short either of the natural or of the positive

right.

Reply Obj. 1: Just as the written law does not give force to the

natural right, so neither can it diminish or annul its force, because

neither can man's will change nature. Hence if the written law

contains anything contrary to the natural right, it is unjust and has

no binding force. For positive right has no place except where "it

matters not," according to the natural right, "whether a thing be

done in one way or in another"; as stated above (Q. 57, A. 2, ad 2).

Wherefore such documents are to be called, not laws, but rather

corruptions of law, as stated above (I-II, Q. 95, A. 2): and

consequently judgment should not be delivered according to them.

Reply Obj. 2: Even as unjust laws by their very nature are, either

always or for the most part, contrary to the natural right, so too

laws that are rightly established, fail in some cases, when if they

were observed they would be contrary to the natural right. Wherefore

in such cases judgment should be delivered, not according to the

letter of the law, but according to equity which the lawgiver has in

view. Hence the jurist says [*Digest. i, 3; De leg. senatusque

consult. 25]: "By no reason of law, or favor of equity, is it

allowable for us to interpret harshly, and render burdensome, those

useful measures which have been enacted for the welfare of man." In

such cases even the lawgiver himself would decide otherwise; and if

he had foreseen the case, he might have provided for it by law.

This suffices for the Reply to the Third Objection.
