Plain-English Summary

Rules change over time, and Rule 86 answers the practical question of when a change governs a case. Every new rule or amendment takes effect on the date the Nevada Supreme Court sets. From that date forward, it applies to newly filed actions as a matter of course. It also reaches back to cases already pending — the default assumption is that everyone litigates under the current rules, not whatever version was in force when the case was filed.

That reach-back has two safety valves. The Supreme Court can specify that an amendment doesn't apply to pending cases, and a court handling a specific case can decline to apply an amendment if doing so wouldn't be feasible or would work an injustice given how far the case has already progressed. The rest of Rule 86 is a running record of every amendment since the NRCP first took effect on January 1, 1953 — useful for tracing which version of a given rule applied on a particular date, but it doesn't change how the rule itself operates going forward.

Frequently Asked Questions

If a rule changes while my case is already pending, which version applies to me?

The amended version generally applies, even to pending cases, unless the Supreme Court says the amendment doesn't reach pending cases or the court finds applying it would be infeasible or unjust.

Can a court refuse to apply a new amendment to my case?

Yes. Rule 86 lets a court decline to apply an amendment to a pending action if doing so isn't feasible or would work an injustice, given the stage the case has already reached.

When did the Nevada Rules of Civil Procedure first take effect?

January 1, 1953, with numerous amendments since then, each on its own effective date set by the Supreme Court.

How do I find out which version of a rule applied to my case on a particular date?

Rule 86(b) lists every amendment to the NRCP by date and by rule number, letting you trace which version was in force at a given point in time.

Does Rule 86 itself change the substance of any other rule?

No. It governs timing and applicability — when rules take effect and whether amendments reach pending cases — not the content of the individual rules.
