That's what I mean with "Constitutional Court is not above the Federal Court".
Unlike the U.S. Supreme Court, the Federal Constitutional Court only deals with constitutional questions. It is decidedly not an appellate court.
And even if you wanted to claim the decision was wrong, a simple error in judgment by another court is not grounds for constitutional review.
