Common Mistakes to Avoid
- Misinterpreting Originalism: Originalism is not about blindly following the original meaning of the Constitution. It allows for reasonable interpretations based on the intent of the framers and society’s evolving values.
- Oversimplifying Judicial Review: Judicial review is not a rubber stamp. The Court carefully weighs the constitutionality of laws and actions, considering legal precedent and evolving societal norms.
- Confusing stare decisis with precedent: Stare decisis is the principle of following prior decisions. However, precedent can be overturned if the Court finds it no longer comports with evolving societal values or constitutional principles.
- Assuming the Supreme Court is always right: The Supreme Court is composed of humans who are subject to biases and limitations. Its decisions are not infallible and can be challenged and overturned.
