The light-rail debate took a buck-passing turn last week as County Chairman Mel Martinez impaneled a seven-member study commission to advise him on the controversial proposal. Led by former Orlando Mayor Bill Frederick, the group is assigned to reread all previous light-rail studies and create a new one by February. The Orlando Sentinel seems to think this means the project is a go -- it praised the commission and its maker in an editorial -- but this result is not guaranteed. Maitland Mayor Robert Breaux, for instance, is a commission member who sued light-rail planners last summer to stop the train. (The suit was thrown out.) Other commission members have not given opinions on the project.
