The function of a ___________ is to determine the facts and apply the relevant law to these facts?

A trial court serves the primary function of determining the facts surrounding a case and applying the relevant law to those facts. This is where the case is initially presented, and evidence is gathered through witness testimonies, documents, and other materials. The trial court evaluates all the information and makes determinations about whether the law has been violated and what the appropriate response should be.

In contrast, appellate courts do not conduct trials or determine facts; instead, they review the decisions made by trial courts for legal errors. Arbitration panels are designed to resolve disputes outside of court but typically focus on the arguments and evidence without the comprehensive fact-finding role of a trial court. Mediation boards facilitate negotiation between parties to reach a settlement but do not make determinations about fact or law; they primarily serve to help the parties construct a mutually agreeable resolution. Thus, the role of a trial court is uniquely centered on the assessment of facts and application of the law, making it the correct answer.
