Chesterfield County Circuit Court Clerk Judy L. Worthington is suing the chief Circuit Court judge in a turf spat, among other things, over the county’s Web site. Worthington complains that in November, Judge Michael C. Allen issued an order authorizing lawyer Aubrey M. Davis Jr. to perform marriages. The order directed that Davis’ name be added to a list of people authorized to do so on the clerk’s page of the county Web site.
