1. Structure
The U.S. legal system is a federal system, meaning it has both federal and state courts.
It is based on the common law tradition, where past court decisions (called precedents) play a major role in shaping the law.
2. Sources of Law
The highest law of the land is the U.S. Constitution.
Other important sources of law include:
Statutes – Laws made by Congress or state legislatures.
Regulations – Rules made by government agencies.
Case law – Decisions made by judges in previous court cases, which guide future cases.
Fill in the blanks
Federal Courts:
District Courts – These are the trial-level courts where federal cases start.
Courts of Appeals (Circuit Courts) – These courts review decisions made by district courts.
U.S. Supreme Court – This is the highest court in the country and has the final say on constitutional issues.
State Courts:
Each state has its own system of courts, including trial courts, appeals courts, and a state supreme court.

4. Types of Law
Criminal law involves the government prosecuting someone accused of breaking the law, with the goal of punishment.
Civil law deals with disputes between individuals or organizations, usually involving money or rights.
Fill in the blanks
The U.S. uses an adversarial system, meaning two opposing sides present their arguments in front of a neutral judge and, in many cases, a jury.
The Constitution guarantees due process, meaning everyone has the right to fair legal procedures.
Judges interpret and apply the law to cases.
Attorneys (lawyers) represent individuals, businesses, or the government in legal matters.
Juries are groups of citizens who listen to the facts of a case and decide on a verdict in many trials.

The Midnight Entry
It was a quiet night in the neighborhood when Officer Daniels received a call from an anonymous tipster claiming that illegal drugs were being used inside a small, unassuming house at the end of Maple Street. The tip seemed credible—over the past few weeks, the police had received several complaints about suspicious activity at that location.
Without waiting for a warrant, Officer Daniels and two colleagues quietly approached the house. The front door was slightly ajar, and they stepped inside. The living room was dimly lit, and voices whispered in hushed tones. As they moved further, they spotted a group of people sitting around a coffee table, passing around small packets and smoking from glass pipes.
The officers quickly seized the evidence: several bags containing white powder, drug paraphernalia, and other materials consistent with illegal drug use. They arrested everyone present and planned to charge them with possession and use of illegal substances.
What do you think the judge should decide? And why?
The Fourth Amendment protects people from unreasonable searches and seizures and generally requires law enforcement to obtain a warrant before entering a private home.
In this story:
The police entered without a warrant.
There’s no mention of an emergency situation (like imminent destruction of evidence or immediate danger) that would justify a warrantless entry.
The anonymous tip, while possibly credible, alone is usually not enough to justify entering a home without a warrant.
Therefore:
The judge should rule that the police entry was unlawful because it violated the Fourth Amendment.
As a result, the evidence obtained during this illegal search is likely to be excluded under the “exclusionary rule.” This rule prevents illegally obtained evidence from being used in court.
Why is this the right decision?
It protects privacy and property rights.
It ensures that police follow proper legal procedures, including obtaining a warrant from a neutral judge.
It prevents abuses of power and protects citizens against arbitrary government intrusion.
Case: Olmstead v. United States (1928)
Background:
In this case, federal agents suspected Roy Olmstead of running an illegal bootlegging operation during Prohibition. Instead of obtaining a warrant, the agents secretly wiretapped Olmstead’s phone lines without physically entering his home or office. The wiretap recordings were used as evidence to convict him.
The Fourth Amendment Issue:
The Fourth Amendment protects against unreasonable searches and seizures, traditionally understood as physical intrusions into a person’s property. But the agents didn’t physically enter Olmstead’s property; they intercepted his conversations remotely.
The Supreme Court’s Decision:
The Court ruled against Olmstead, holding that because there was no physical intrusion, the wiretapping did not violate the Fourth Amendment. The evidence was admissible, and Olmstead’s conviction stood.
Why it was criticized:
This decision was seen as a bad ruling by many because it ignored the privacy implications of the wiretap. It allowed government surveillance without a warrant or probable cause, creating a loophole in Fourth Amendment protections.
Later developments:
The ruling was overturned in Katz v. United States (1967), where the Supreme Court recognized that the Fourth Amendment protects people, not just places, establishing the “reasonable expectation of privacy” standard.

Before a lawsuit can proceed, the plaintiff must serve a claim to the defendant with the necessary legal documents.
The court will hear a case involving the parties to present their arguments and evidence.
After reviewing all the evidence, the judge may find in favour of the plaintiff or the defendant depending on who has the stronger case.
The defendant has a limited time to respond to a claim or dispute the allegations made in the lawsuit.
If a party wants to start legal proceedings, they must first issue a claim in the appropriate court and pay a fee.
The judge will give a judgement based on the facts and applicable law, explaining the reasoning behind the decision.
To ensure compliance, the judge may make an order directing one party to take specific actions or stop certain behaviour.
