A more thorough explanation:

The public-records exception is a legal rule that allows certain public records to be used as evidence in court, even if they would normally be considered hearsay. This exception applies to the contents of public records or the absence of a record that would normally be kept in public archives.

For example, if a police officer testifies in court about a report they wrote, that report can be admitted as evidence under the public-records exception. Similarly, if a party claims that a certain document should exist in public records but cannot be found, the absence of that document can also be admitted as evidence under this exception.

The public-records exception is important because it allows important information to be used in court, even if the person who originally created the record is not available to testify. However, not all public records are admissible under this exception, and it is important to consult with an attorney to determine whether a particular record can be used as evidence.
