The Boston Harbor Relamation Project, which began in the 1980s, has been at the centre of the debate on the legality of PLA.   When the Massachusetts Water Resources Authority decided to use a PLA for the project that provided only for union activities, the Associated Builders and Contractors of Massachusetts/Rhode Island, Inc. challenged their legality and asserted that the use of a PLA was prohibited by the National Labor Relations Act.  In 1990, the Federal Court of Appeals for the First Circuit ruled that the Boston Harbor Court violated federal labour law because of its union work.  Government-mandated AEPs have been the subject of much discussion, particularly for publicly funded projects.  The implementation of project work contracts is supported by construction unions and by some political figures who say that it is necessary to ensure that large, complex projects are completed on time and on time.  In the view of those who support the use of such agreements, THE PLA allows project owners to control costs and ensure that there is no disruption to the construction plan, for example. B by strikes.  In particular, TPC proponents refer to the inclusion in the agreement of clauses that agree to create committees to address labour management issues that deal with planning, quality control, health and safety and productivity issues during the project.
 They also note that the AEPs ensure that the recruited workforce is trained and of high quality.  The use of PLA in large private projects such as the construction of gillette Stadium of the New England Patriots is cited as an example of how PLA project owners are helping to meet tight deadlines, according to fans.  In addition to the reported benefits to project owners, PLA proponents also argue that the use of PLA has a positive impact on local communities by setting targets for local hiring and education provision.  With the February 2009 stimulus package, which provided approximately $140 billion for federal, regional and local construction projects, government-mandated LEPs for public works projects were widespread at the local and national level from 2009 to 2011. Government officials and legislators have argued over the use of PLA mandates for projects in states such as Iowa, Oregon, Ohio, California and others.   Some municipalities voted to ban the use of mandatory LPOs for taxpayer-funded construction projects, including election initiatives in Chula Vista, Oceanside and San Diego County, California, in 2010, which led to a ban on officials hiring or banning PPPs for government projects.  In 2011, contractors filed with the Government Accountability Office against government-mandated PLAs for construction projects in New Hampshire, New Jersey, Pennsylvania and Washington, D.C. These protests led to the departure of federal warrants from tenders.  Although the 2002 Court of Appeal`s decision upheld the executive order prohibiting federal projects from using LBAs, some states and counties were allowed to use LTCs for certain public works funded by government and local revenues. These LASs have received opposition from organizations such as the Associated Builders and Contractors and the Black Contractors Group.  A remarkable example of pro-PLA legislation was passed in New Jersey, which passed legislation in 2002 authorizing the use of LPAs for certain state-funded projects.
 “Opponents of state-mandated GPs argue that these controversial agreements end fair and open competition and prevent non-unionist local contractors from working on projects in their own communities, effectively limiting competition during the tendering process and increasing construction costs,” said David G.
