Common questions
Frequently Asked
4
What distinguishes a substantial risk from a mere possibility in criminal intent analysis?+
A substantial risk exists when the defendant consciously disregards an obvious probability that the owner will lose the property. Intent is satisfied if the planned dealing creates that level of exposure rather than a remote chance of loss.
How is substantial risk used to define serious bodily harm in tort and criminal law?+
Serious bodily harm includes any injury that creates a substantial risk of fatal consequences or produces permanent loss of an important bodily function. The focus is on the gravity of potential results rather than the degree of force actually applied.
When does a law enforcement inducement create a substantial risk for entrapment purposes?+
Entrapment occurs when official methods of persuasion create a substantial risk that persons other than those ready to offend will commit the crime. The test examines whether the inducement would likely cause a law-abiding person to act unlawfully.
What role does substantial risk play in determining necessary parties under Rule 19?+
A person must be joined if their absence would leave an existing party subject to a substantial risk of incurring double or inconsistent obligations. The court orders joinder to prevent that exposure from materializing.
