The School Board is being told it doesn't have the right to appeal Mullaney's decision. Individual board members might be able to go to court on their own, but it's questionable if they would have the legal standing to do so. And the local bus contractors could challenge Mullaney's ruling in court, but a long court fight would be expensive and the local bus contractors aren't exactly flush with cash. When the smoke clears from all of this, and it will, the role of the general counsel and the city charter need to be re-examined. The power of being an elected official should include the right to do stupid things without being overturned by an appointed official.
Voters can do the overturning.
That's why there's always another election. Enter words describing a concept or keywords.
