Infraction Procedure Guide
The Magic™ Infraction Procedure Guide (IPG) provides judges the appropriate penalties and procedures to handle rules violations that occur during a tournament held at Competitive or Professional Rules Enforcement Level (REL), as well as the underlying philosophy that guides their implementation. It exists to protect players from potential misconduct and to protect the integrity of the tournament itself. Rules violations usually require a penalty or they are unenforceable. Tournaments run at Regular REL use the Judging at Regular REL document.
The latest version of the IPG can always be found on the WPN site at http://wpn.wizards.com/en/resources/rules-documents/244.
