What does the privilege of necessity allow a person to do?

The privilege of necessity allows a person to interfere with another's property to prevent greater harm or to address an imminent danger. This legal principle recognizes that, in certain emergency situations, an individual may need to take actions that would otherwise constitute a tort, such as trespassing or damage to property, in order to avert a more significant harm.

For instance, if someone needs to trespass onto another person's land to rescue a person in danger or to prevent a fire from spreading, the privilege of necessity provides a defense against any potential legal claims that could arise from this interference. The law balances the interest in property rights with the need to protect individuals and the public from harm.

In contrast, entering property without consequence implies a blanket allowance that does not typically exist under the privilege of necessity, as there are conditions and justifications that must be met. Claiming ownership of another's property misrepresents the scope of necessity, as that would involve a legal transfer of rights rather than a temporary interference to prevent harm. Conducting activities with full immunity would similarly suggest a lack of accountability for the actions taken, which does not align with the principle that necessitates a justification for the interference.
