# Class 42 — Syntax Error or Access Rule Violation

## Shared meaning {#meaning}

The first two characters `42` identify `Syntax Error or Access Rule Violation`. The statement violates syntax or an access rule. A class gives a directory-level family; each member still needs its own message, transaction aftermath, and response evidence.
