Which statement about common law crimes is correct?

• A. They have fixed, universal definitions.
• B. They cannot be prosecuted in modern courts.
• C. They require a specific statute to define the crime.
• D. Their definition can limit the scope of their use.

Answer: (D)

Common law crimes are defined by judicial decisions rather than written statutes, so their boundaries come from precedent and can vary across jurisdictions and over time. They are still prosecutable in modern courts, though many have been codified or limited by statute. A key point is that the elements and scope of a common law offense—what must be proven to convict—directly determine when the offense can be charged, which means the definition can limit how broadly it can be used. Because the boundaries are set by interpretive rulings, the offense may be narrowed or expanded as courts refine the elements.
