CONCORD, N.H. — Judge Robert Lynn says he has both the judicial and administrative experience to hit the ground running and lead the New Hampshire Supreme Court through a time of transition.

Republican Gov. Chris Sununu nominated Lynn earlier this month to replace Chief Justice Linda Dalianis, who is retiring April 1 after reaching the mandatory retirement age of 70. Lynn, who has served as an associate justice on the court for seven years, will hit that age in less than two years.

At a public hearing Monday before the Executive Council, colleagues from throughout the court system praised Lynn as a talented legal analyst, committed to treating everyone with respect. Though an anonymous court staffer sent a letter describing him as intimidating, he and others strongly disagreed.
