(CNN) A West Virginia House panel adopted articles of impeachment Tuesday against all four state Supreme Court justices, escalating a widening scandal in the state's judicial system.

The 14 articles of impeachment , adopted by the House Committee on the Judiciary, accuse Chief Justice Margaret Workman and Justices Allen Loughry, Robin Davis and Elizabeth Walker of failing to carry out the court's administrative duties and wasteful spending during office renovations.

Half the articles of impeachment deal solely with Loughry, who was indicted in June on 22 criminal federal charges , including fraud, false statements and witness tampering. Workman and Davis also may face impeachment for wrongfully approving the overpayment of senior judges.

The articles of impeachment -- along with criminal charges faced by Loughry and another, retired justice -- show that the state Supreme Court had a real problem, Judiciary Committee Chairman John Shott, a Republican, told CNN by phone.

"They think that they are superior and don't need to hold restraint over the taxpayer money they are entrusted with," he said.
