Common Examples

Officer Approves Acquisition
Roberto Reyes, an officer at Regal Apparel, reviewed a short memo from management recommending the purchase of a rival brand. He approved the deal without seeking further financial analysis because he believed it served the company's long-term growth. The court later assessed whether that belief aligned with what a reasonable officer in his position would conclude under the circumstances.
Judge Permits Ex Parte Scheduling
Judge Raphael Rivera contacted counsel for one party to reset a hearing date after a sudden medical emergency. He concluded that the brief discussion would not give either side an advantage on the merits. The rule required him to confirm that a reasonable judge would reach the same conclusion on the facts known at the time.

Lawyer Considers Withdrawal
Roger Ramirez learned that his client planned to use the lawyer's services to submit false loan documents. He determined that continuing the representation would assist criminal conduct. The rule permitted withdrawal once he formed that reasonable belief based on the information available to him.
Officers Enter Home for Aid
Officers Regina Robinson and Rajesh Rao responded to a 911 call reporting a possible assault inside a residence. They heard cries and saw blood on the doorstep, leading them to conclude an occupant needed immediate help. The emergency aid exception allowed entry when those facts supported an objective belief that injury was imminent.
Buyer Relies on Expert Opinion
Ralph Richardson purchased rare artwork after the seller's appraiser stated it was an original. Richardson had no special expertise in the field and reasonably believed the appraiser possessed superior judgment on authenticity. The rule permitted reliance on that opinion under the stated circumstances.
Actor Assesses Danger
Raven Logistics' security guard observed a trespasser approaching a restricted area at night while carrying an object that appeared to be a weapon. The guard concluded that the individual posed an immediate threat based on the visible circumstances. The standard required that a reasonable person in the same position would reach the same conclusion.
Common questions
Frequently Asked
5
Does the standard require only a subjective belief or an objective component as well?+
The standard requires both. The actor must actually hold the belief, and the known circumstances must be such that a reasonable person would hold it too.
How does the standard apply when an officer decides whether a transaction benefits the corporation?+
The officer must hold a subjective belief that the action serves the corporation's best interests, and that belief must be one a reasonable officer in the same position would form after considering available information.
When may a lawyer withdraw because a client is pursuing criminal conduct?+
Withdrawal is permitted when the lawyer reasonably believes the client's course of action involving the lawyer's services is criminal or fraudulent, judged by what a reasonable lawyer would conclude from the facts known.
What must officers show to enter a home under the emergency aid exception?+
Officers must possess an objectively reasonable belief, based on specific facts, that an occupant is injured or imminently threatened with injury. Subjective motives do not control the analysis.
When is reliance on an opinion justified under contract law?+
Reliance is justified when the recipient reasonably believes the person offering the opinion has special skill or objectivity compared with the recipient on the subject matter.
