Assertion (A): The cost of the justice system in adversarial system falls upon the parties.
Reasoning (R): Parties with better resources are able to access justice by hiring competent lawyers and presenting sophisticated evidences which may not be immediately available for parties that lack these resources.

Both A and R are correct and R is not the correct explanation of A.

The cost of the justice system in adversarial system falls upon the parties. This creates an in-built discrimination amongst the litigants. Parties with better resources are able to access justice by hiring competent lawyers and presenting sophisticated evidences which may not be immediately available for parties that lack these resources. Accessibility and affordability to justice are important challenges for the adversarial system of dispute resolution.
