Some in the Massachusetts legal community are concerned that dozens of experienced judges may retire this year, making way for new judges who will take a while to get up to speed and slow down the justice system.

A $30,000 pay raise for judges takes effect July 1, prompting some to speculate that many will retire once the raise takes effect because they will be eligible for a higher pension.

Criminal defense attorney John Amabile says that a lot of new judges with little experience could ``dramatically affect the quality of the administration of justice.'' Others see turnover as good.

Martin Healy, chief legal counsel of the Massachusetts Bar Association says he sees it as ``an infusion of new blood into a staid justice system.''
