Legal Definitions - extrapolation

Extrapolation refers to the process of inferring or estimating unknown information, values, or principles by extending known facts, data, or established precedents. It involves taking what is understood in one context and applying or predicting its implications in a different, but related, situation.

• Example 1: Applying a Legal Principle to New Technology

  Imagine a state law that prohibits "operating a motor vehicle while using a handheld communication device." A new case arises where a driver was cited for texting using a smartwatch. The law was written before smartwatches were common. A prosecutor might argue that the intent of the law, which aims to prevent distracted driving from handheld devices, should be extrapolated to include smartwatches. The court would then decide if this extension of the legal principle is valid, considering the smartwatch's function as a communication device and its potential for distraction.

  This illustrates extrapolation because an existing legal principle (prohibiting distracted driving via handheld communication devices) is being extended from explicitly mentioned devices (like phones) to a new, similar technology (smartwatch) that wasn't specifically contemplated when the law was drafted.

• Example 2: Estimating Future Financial Damages

  In a personal injury lawsuit, a plaintiff who was a promising young architect suffered an injury that prevents them from continuing their career. To determine future lost income, an economic expert witness might extrapolate the plaintiff's potential future earnings. They would do this by analyzing the plaintiff's past salary, typical career progression for architects of similar talent and experience, industry growth trends, and average earnings for successful professionals in that field.

  This demonstrates extrapolation by estimating an unknown future financial value (lost income) based on known past data (plaintiff's earnings, industry averages, career trajectory) and projecting those trends forward to predict what would have happened without the injury.

• Example 3: Applying Regulatory Standards to Novel Substances

  Consider a scenario where a manufacturing company develops a new chemical compound that is not explicitly listed in existing environmental regulations regarding hazardous waste disposal. However, the compound shares several characteristics with other chemicals that *are* regulated. Environmental protection agencies might extrapolate from the existing regulations for chemically similar compounds, or from the general principles of environmental protection outlined in the law, to determine appropriate disposal methods and assess potential violations for the new compound.

  Here, extrapolation involves applying established legal principles and regulatory guidelines for known substances to a novel substance that falls under the general scope but isn't explicitly named, based on its chemical properties and potential environmental impact.
