Overturning a lower court ruling, the Massachusetts Supreme Court granted former Gov. Edward J. King a jury trial of a libel charge brought against the Boston Globe for one of several editorial columns and cartoons. King, the state's Democratic governor from 1979 through 1982, filed suit five years ago claiming that three cartoons and four columns published during his tenure libeled him and weakened his ability to govern. Superior Court Judge James P. Lynch Jr. granted summary judgment for the Globe last year. In a 5-0 decision, the high court upheld the majority of Lynch's ruling. But it overturned his decision on a column by David Farrell.
