Bill (Law) Idea: Make Gambling Illegal
The Bill will be proposed and written by the Legislative Branch, which is Congress and the HOR(House of Representatives). It first has to be approved by the HOR before moving to the Senate. Once the Senate approves, it moves to the executive branch (President). If the president approves, it moves to the Judicial branch to be interpreted (Is the bill constitutional?). If the Judicial branch decides that the bill it constitutional, it’s passed!
The executive branch is able to veto a bill.
Feel free to choose a different law, it’s the same process. Hope I helped :)
