Drafting errors sometimes occur in legislation. Usually these errors are minor, such as incorrect punctuation or capitalization, and the meaning is unaffected. But sometimes the matter is more substantive. Sometimes courts refuse to apply legislative intent that conflicts with the text of the law, as in the case of the Virginia General Assembly accidentally repealing the exemptions of almost all industries from the statute requiring employers to allow employees not to work on Sabbath. It was necessary for the legislature to re-assemble for a special session to correct the error.
