Gov. Deval Patrick pledged to reform the way business gets done on Beacon Hill but continues to fill his administration with loyalists and stock the state judiciary with campaign supporters.

The latest Patrick backer to land on the bench is Kenneth King, a Newton lawyer and associate professor at Suffolk Law School who was tapped by the governor this week for the Middlesex Juvenile Court. Records show King gave Patrick’s campaign $200 in 2005 and $100 in 2006.
