Specific performance.
Specific instruction.

Both sound like plain English. Injunction is the word that would sound like a legal jargon.

A specific performance has the force of law that a specific instruction does not.

Christians sometimes say biblical injunction to refer to the "Thou shalt not" of God's laws. But not all are "Thou shalt not". Some are "Thou shalt". These would be biblical specifuc performances. Together with the biblical injunctions, they form the Ten Commandments. That's God's Laws. 

Executing a specific instruction as if it were a court order, a specific performance, is to accord to it the highest level of obedience.
