A former Holland & Knight partner who has waged a yearslong court battle against the firm over what he claims was his unfair dismissal from the partnership in 2002 received a further setback: a bill for $351,163 that a court ruled he now owes his one-time professional home.

John Weir, who joined Holland & Knight in 1997 through its merger with Haight Gardner Poor & Havens and at one point led the firm’s New York labor and employment practice, sued the firm in New York federal court in 2005, claiming he was let him go because of his age — 55 at the time — and because the firm didn’t want to pay retirement benefits he claimed.
