What term describes judicial decisions that set precedents for legal principles?

The term that describes judicial decisions which set precedents for legal principles is "case laws." Case law refers to the body of law that is established by the outcomes of previous court cases. Essentially, when courts interpret statutes, constitutional provisions, or regulations, their rulings become part of the legal framework that guides future cases. These decisions are crucial because they create legal precedents that other courts may rely on in deciding similar issues, thereby ensuring consistency and predictability in the law.

Legal verdicts refer specifically to the outcomes or judgments rendered in individual cases rather than the broader principle-setting function that case law serves. Court inquiries generally involve investigations into certain legal matters but do not constitute the legal precedents themselves. Judicial reviews are processes by which courts examine the actions of other branches of government or administrative agency decisions, but they do not specifically create precedents akin to case law. Thus, the term "case laws" is the most precise and correct choice in this context.
