Answer: The executive branch of the government lacks the power to independently pass or veto laws. The executive branch, usually headed by the president or another equivalent executive leader, is in charge of enforcing and carrying out the laws that the legislative branch has established. This is the case in the majority of democratic systems.
By putting out legislation or by exercising its veto authority (if applicable) to block a law approved by the legislature, the executive branch can have an impact on the legislative process. However, the legislative branch, not the executive branch, ultimately has the power to pass or veto laws.
