Pengisian jabatan presiden dan wakil presiden merupakan aspek utama pada sistem pemerintahan presidensial. Saat ini, mekanisme pengisian jabatan presiden dan wakil presiden Indonesia dilakukan melalui pemilihan umum. Namun, UUD NRI 1945 masih memberikan kewenangan kepada Majelis Permusyawaratan Rakyat untuk menyelenggarakan sidang pemilihan wakil presiden jika terjadi kekosongan jabatan atau pemilihan jabatan presiden dan wakil presiden jika terjadi kekosongan jabatan secara bersamaan sebagaimana menurut Pasal 8 ayat (2) dan ayat (3) UUD NRI 1945. Tulisan ini dihasilkan melalui penelitian normatif dengan metode kualitatif yang menjadikan sumber-sumber hukum sebagai landasan utama. Kesimpulan yang didapatkan adalah bahwa adanya kewenangan yang dimiliki oleh Majelis Permusyawaratan Rakyat dalam memilih lembaga kepresidenan sebagaimana menurut Pasal 8 ayat (2) dan ayat (3) UUD NRI 1945 merupakan pelaksanaan prinsip ‘checks and balances’ yang dibangun oleh UUD NRI 1945 dalam rangka penguatan sistem presidensial. Oleh sebab itu, penguatan sistem presidensial terkait kandungan Pasal 8 ayat (2) dan ayat (3) UUD NRI 1945 kedepannya perlu diatur secara komprehensif dalam suatu undang-undang terkait lembaga kepresidenan.
