This section covers pivotal cases involving religious freedom in schools and student expression rights, including Engel v. Vitale, Wisconsin v. Yoder, and Tinker v. Des Moines.
Vocabulary The Establishment Clause prohibits government from establishing an official religion or favoring one religion over others.
Highlight The Tinker decision established that students don't "shed their constitutional rights at the schoolhouse gate."
Example In Wisconsin v. Yoder, Amish parents successfully argued that requiring their children to attend school beyond 8th grade violated their religious freedom.
Definition Prior restraint refers to government censorship of speech before it occurs, which faces a heavy presumption against its constitutional validity.
The final section examines crucial cases involving press freedom and criminal defendants' rights, including New York Times v. United States and Gideon v. Wainwright.
Highlight The Pentagon Papers case (New York Times v. United States) reinforced strong protections for press freedom against government censorship.
Quote "States must provide attorneys for defendants who can't afford one" - a key principle established in Gideon v. Wainwright.
Example In Schenck v. United States, the Court established the "clear and present danger" test for limiting speech.
Definition The incorporation doctrine applies Bill of Rights protections to state governments through the Fourteenth Amendment.
The third page examines landmark cases involving personal rights, including reproductive rights, racial segregation, and Second Amendment rights. These cases represent significant developments in civil rights jurisprudence.
Highlight Brown v. Board of Education overturned the "separate but equal" doctrine, marking a turning point in American civil rights history.
Definition Incorporation refers to the process of applying Bill of Rights protections to state governments through the 14th Amendment.
Example McDonald v. Chicago extended Second Amendment protections to state and local governments, building on the D.C. v. Heller decision.
These two landmark Supreme Court cases established crucial precedents regarding federal authority and state rights. McCulloch v. Maryland addressed the scope of Congress's powers, while U.S. v. Lopez examined limits on federal regulation under the Commerce Clause.
Definition The Necessary and Proper Clause, also known as the Elastic Clause, gives Congress implied powers beyond those explicitly stated in the Constitution.
Highlight In McCulloch v Maryland, Chief Justice John Marshall's decision established two fundamental principles Congress's power to create a national bank and states' inability to tax federal institutions.
Example The U.S. v Lopez decision marked the first time since the New Deal that the Supreme Court limited Congress's power under the Commerce Clause, striking down the Gun-Free School Zones Act.
Quote "The supremacy clause asserts that the national government is superior to state governments when the two conflict."

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
