Whether Isidore's description of the quality of positive law is appropriate?

❌ Objection 1 : It would seem that Isidore's description of the quality of positive law is not appropriate, when he says (Etym. v, 21): "Law shall be virtuous, just, possible to nature, according to the custom of the country, suitable to place and time, necessary, useful; clearly expressed, lest by its obscurity it lead to misunderstanding; framed for no private benefit, but for the common good." Because he had previously expressed the quality of law in three conditions, saying that "law is anything founded on reason, provided that it foster religion, be helpful to discipline, and further the common weal." Therefore it was needless to add any further conditions to these.

❌ Objection 2 : Further, Justice is included in honesty, as Tully says (De Offic. vii). Therefore after saying "honest" it was superfluous to add "just."

❌ Objection 3 : Further, written law is condivided with custom, according to Isidore (Etym. ii, 10). Therefore it should not be stated in the definition of law that it is "according to the custom of the country."

❌ Objection 4 : Further, a thing may be necessary in two ways. It may be necessary simply, because it cannot be otherwise: and that which is necessary in this way, is not subject to human judgment, wherefore human law is not concerned with necessity of this kind. Again a thing may be necessary for an end: and this necessity is the same as usefulness. Therefore it is superfluous to say both "necessary" and "useful."
