Which legal term is considered a secondary source of law and not as authoritative as "stare decisis"?

The correct choice reflects the understanding that "jurisprudence constant," while it may inform legal interpretations and principles, does not hold the same authoritative weight as "stare decisis." Stare decisis is a legal doctrine that compels courts to follow established precedent, ensuring consistency and predictability in legal decision-making.

"Jurisprudence constant" refers to a body of authoritative legal principles that have been consistently applied over time, but it is not binding in the same way that stare decisis governs judicial decisions. As a secondary source, it may be influential and can be referenced for guidance, but it does not have the force of law as established case law does.

In contrast, canon law pertains to the laws of the Church, and while "case law" and "precedent" directly involve judicial decisions guiding future cases, they are pivotal in forming primary sources of law. Therefore, the difference lies in their respective authority and the weight they carry within the legal framework, making "jurisprudence constant" a correct answer as a secondary source.
