Since signing the Settlement Agreement in 2006, the MBTA has collaborated with the Plaintiffs and GBLS to ensure that all terms agreed to in the settlement are upheld. This led to the signing of the Joint Assessment in 2010, which was the first official review of the MBTA’s performance since the 2006 settlement. More recently, the 2013 Joint Assessment was signed on March 14, 2014 and concluded an enormous effort by both the MBTA and the Plaintiffs to ensure a detailed accounting of progress made since the settlement, and to highlight what still needs to be done in the future.
