Can a husband appeal a final major divorce ruling issued for his wife, based on his intention to discipline her when he informed her that she was "in her waiting period from today," even though the court considered it a third divorce?

What was issued by the questioner is a metaphor for divorce (kinayah). Divorce occurs with it if there is intent, even if the intention was to discipline. Scholars have differed regarding explicit metaphors (kinayah zahirah) and what results from them. It appears that the judge who ruled that what was issued was a divorce (talaqah) was of the opinion that an explicit metaphor does not require intent, and that the circumstantial evidence indicates that it was a divorce. The judge's ruling is binding and resolves the dispute.
