The Qadhi al-Mazaalim has the mandatory power to remove any ruler or civil servant, and He also has the right to remove the Khaleefah.

The Qadhi al-Mazaalim has the right to remove the rulers, for the ruler is appointed by a contract, known as the contract of assignment which is also called the contract of appointment (Taqleed). The Khaleefah has the right of the Wilayah that is the ruling, and He has the right of appointment, which is the assignment, and the appointment can only be done with clear wording. Thus the removal of the ruler appointed by the Khaleefah would be a termination of that contract, and the Khaleefah undoubtedly reserves that right. This is because the Messenger of Allah (pbuh) appointed the Wulah and removed them. The Khulafaa’ Ar-Rashidoon also appointed the Wulah and removed them; the Khaleefah could also delegate to those whom He appointed the right to appoint and remove. However, the court of Mazaalim does not have the right to remove the rulers on behalf of the Khaleefah, for it does not act on his behalf in appointing and removal. it rather acts on his behalf in looking into the Mazaalim. So if the presence of that ruler in his Wilayah was a Mazlema, the court has the right to remove that Mazlema i.e. it has the right to remove that ruler from office. Therefore, its power to remove the ruler is not done on behalf of the Khaleefah, but merely to remove the Mazlema. So the one whom it judges to be removed should be removed, even if the Khaleefah does not agree with the judgement. This is because the removal of that ruler would be the removal of a Mazlema, and this applies to everyone, including the Khaleefah, for the judgement of the judge applies to everyone. As for its power to remove the Khaleefah, this would also be by a judgement aimed at removing a Mazlema. This is because if the Khaleefah were in a situation that necessitates his removal, or in a situation as a result of which He should be removed, then his stay in office would be a Mazlema. It is the court of Mazaalim that judges the removal of Mazaalim, so it would order his removal. Therefore, the judgement of the court of Mazaalim to remove the Khaleefah would be a judgement aimed at removing a Mazlema.
