This summary is not the rule. The rule text controls.
Lawyers have a duty to keep cases moving forward without unnecessary delay. If a lawyer can push a case toward a fair resolution faster, they should do that, as long as it still serves their client's best interests.
This means lawyers can't drag out a case just to run up legal fees, wear down the other side, or cause problems for someone else involved in the case. Delay tactics used purely for strategic advantage or to make the process harder on the opposing party go against this rule.
That said, the rule doesn't force a lawyer to rush through a case or skip steps that actually help their client. If more time is genuinely needed to prepare, gather evidence, or protect the client's rights, that's still allowed. The key idea is that lawyers should avoid delay for delay's sake, while still doing what's necessary to represent their client well.
