فوجب أن يجب على شريك الأب؛ لأن الأب لم يرفع عنه القلم
Then retaliation should be required against the father's partner, because the father is not exempt from legal accountability.
The response exposes the earlier inference's weakness. If nonliability of the minor's partner is explained solely through the minor's exemption, that explanation cannot by itself settle the case involving a legally accountable father, whose situation has its own specific legal treatment.
A particular reason for the nonapplication of a ruling does not finish the legal analysis. One must identify the evidence for the liability rule, and then the relevant exemption or impediment in each distinct case.
