State GOP attacks MT Supreme Court in mailer Chief Justice McGrath responds to questions MTN News and last updated 2021-05-03 19:41:04-04 HELENA â The state Republican Party has sent a mailer attacking the Montana Supreme Court, saying the court needs to be investigated for âquestionable activitiesâ related to lobbying and its release of documents. The mailer, sent late last week, is the latest salvo in the GOPâs assault on the reputation of the Montana judiciary â an effort also infused with the partyâs attempts to exert more control over state judicial appointments. Montana Supreme Court Chief Justice Mike McGrath also sent a letter Friday to Republican leaders of a committee investigating the judiciary, saying neither the high court nor the judiciary had violated any rules or laws regarding lobbying or e-mail procedures.
