When is an employee subject to removal due to an illegal selection?

An employee is subject to removal due to an illegal selection when both conditions outlined are met. First, if the employee entered on duty illegally, it indicates that their hiring did not follow lawful procedures, which is a fundamental reason for potential removal. Second, if no legal alternative can be identified, it implies that the situation cannot be rectified through other means, reinforcing the need for removal to maintain the integrity of the hiring process. Therefore, the combination of both entering on duty illegally and the absence of legal alternatives substantiate the basis for removal, making this choice comprehensive in addressing the reasons for illegal selection.
