Hasty counsels are rarely prosperous.

Explanation

(English-origin maxim.) Decisions made in haste are prone to error — the law favors deliberation over impulse, and precipitate counsels yield poor results.

Where this applies

• A city council rushes through an emergency ordinance overnight without public comment, and the law is later struck down for vagueness — haste produced a defective result.
• A judge issues a restraining order within minutes of hearing one side's argument, and the appellate court reverses because key facts were overlooked in the rush.
• A corporate board votes on a major merger during a five-minute phone call without reviewing the financials — the hasty decision leads to shareholder losses and litigation.
