A more thorough explanation:

The borrowed-statutes doctrine is a legal principle that states if one state adopts a statute identical to that of another state, any settled judicial construction of that statute by the courts of the other state is binding on the courts of the state that later enacts the statute.

For example, if State A adopts a statute identical to that of State B, and the courts of State B have already interpreted and applied that statute in a certain way, the courts of State A must also interpret and apply the statute in the same way.

A borrowing statute is a legislative exception to the conflict-of-laws rule holding that a forum state must apply its own statute of limitations. A borrowing statute specifies the circumstances in which a forum state will apply another state's statute of limitations.

For instance, if a person is injured in State A and wants to file a lawsuit, but the statute of limitations in State A has expired, they may try to file the lawsuit in State B, where the statute of limitations has not yet expired. However, if State B has a borrowing statute that requires it to apply State A's statute of limitations in this situation, the person's lawsuit may be dismissed.
