No federal court in the US can pass laws, only Congress and the state legislatures can do that. The US govt is divided into 3 branches:
1. Executive (president/White house/all associated employees/armed forces)
2. Legislative (Congress, which is comprised of House of Representatives and the Senate)
3. Judicial (federal courts and the Supreme Court)
The federal courts can make rulings and these can be considered legal precedent, but not necessarily laws. The courts can, however, overturn laws, but it is up to Congress to actually pass laws. Congress can review the courts' decision and revise or overturn current laws (particularly if the courts rule something as illegal/unconstitutional). Congress either passes potential bills into laws or shoots them down. The president has the decision of either approving laws pass to him/her by Congress, or vetoing them, which can be overridden by a majority vote in Congress (not sure what the exact percentage required is). The president also possesses the power of executive order, which allows them to issue directives that are like laws but not quite the same. There are also federal agencies which can institute policies/rules/regulations, but these arent laws either.
Also, the US is *NOT* a democracy (which means direct rule by the people), instead it is a republic (which means representatives are elected/appointed to represent the people) with democratic qualities.
The 50 states are structured in a manner that is similar to the US govt, and have their own laws which are only applicable statewide. The US Constitution gives the states a certain degree of autonomy, but the states still must adhere to certain federal laws. And there are situationsvin which state laws can override federal laws or vice versa.
I'm not an expert in the politics/govt of this nation, but I did take history/civic classes in school (and did very well in them), so I have an above average understanding of how things work. I was my history teacher's favorite student, he was known for being extremely strict and experienced. I aced almost every subject except math, and came close to graduating with top honors, until I was arrested for something I dont feel obliged to talk about. A good while later I enrolled in university with the intention of getting a degree in business management/administration, but was forced to drop out due to economic circumstances (and not getting along well with staff/students due to my antisocial personality and seeming inability to cope with most people). I'm most skilled/interested in computing and technology in general.
