Hambatan atau alasan-alasan yang mempengaruhi tidak terimplementasinya putusan MK berdasarkan tahun putusan 2018 sampai dengan 2020 ialah faktor keuangan dan ekonomi; politik; komunikasi; kejelasan putusan MK; kekuatan keempat dalam checks and balances; kelalaian; Putusan MK tidak memiliki upaya paksa dalam eksekusinya, sehingga adressat putusan dalam beberapa putusan terkesan mengabaikan putusan MK; DPR dan Presiden memerlukan waktu untuk membahas rencana perubahan/pencabutan terhadap frasa/pasal/ayat dari suatu Undang-Undang yang telah diuji oleh MK; Adanya Prolegnas yang menjadi target DPR.
