In an adversarial legal system, what is the primary role of each side?

In an adversarial legal system, the primary role of each side is to act in its own interest, which typically involves presenting evidence and arguments to support their case. This system is grounded in the belief that the best way to achieve justice is through a robust contest between two opposing advocates who each represent their client's interests. Each party strives to highlight the strengths of their case while undermining the opposing side's position, allowing the court to make a decision based on the strongest argument and evidence presented.

This competitive framework is essential because it ensures that all relevant facts and legal arguments are brought to light, enabling a fair and impartial adjudication by the judge or jury. The system relies on the premise that the truth and justice emerge from this adversarial contest, rather than through mediation or other means of conflict resolution.
