Have to look again but I don’t think he said “to enforce the psak”, just to present it.
Looking quickly it seemed the psak lgaresh was based on the fact that the marriage wasn’t reconcilable. That isn’t accepted as grounds for kefiya.
Since the ruling only quotes excerpts (which seem to be translated from Hebrew) it is hard to say, since the court quoted what they felt was relevant, not necessarily what is halachicaly important.
But I understood the mention of "obligated" and "must" as the basis for a tzav kefiya.
If the case being discussed is the one I am thinking about, the husband was kicked out of his shul until he gives a get.
