The existence of conditional decisions becomes dynamic in constitutional review, including their use in procedural constitutional reviews. Constitutional Court Decision No. 91/PUU-XVIII/2020 is the first decision to grant the petition and use a conditional decision model. Unfortunately, as mentioned earlier, using the conditional decision model in the decision results in discourse among various parties, including government institutions, law enforcers, academics, and the general public.

This research indicates that the conditional decision is incompatible with formal constitutional review.
