The legislative branch starts out with an idea writing it out and giving it to the court presenting their case and turning it into a bill. In conclusion the legislative branch has to give reasons to the government in order to pass it to a bill.
The Judical branch gets the ''bill'' and debates about it. If they like it they send it of to the president to either ''veto'' or say yes to it
The executive branch is basically like the president he can veto it or say yes to the bill and make it a law.
