On October 23, 1992, while the Boston Harbor case was still on trial, President George H.W. Bush signed Executive Order 12818 prohibiting federal authorities from carrying out union work exclusively for construction projects.  Bush`s ordinance prohibiting the use of LTCs in federal construction projects.  The Clinton administration rescinded that order when President Bill Clinton issued Executive Order 12836 in February 1993, shortly after taking office.  This contract allowed federal authorities to finance construction projects for which contractors needed a PLA.  A month later, the U.S. Supreme Court unanimously upheld the implementation of public projects agreements in the Boston Harbor Cleanup case.  The Supreme Court held that if the government was in the role of a regulatory authority, it was not in a position to require the use of PLA in accordant to the principles of pre-emption of labour law, but it could choose to do so as a market player without being anticipated by the National Labor Relations Act.  The Court did not consider whether state-imposed APAs were legal under the federal or federal competition laws. The decision has led to increased use of ATPs in public works projects in the United States Government-mandated PPEs 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.

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.  Supporters say that LSPs can be used by owners of public projects such as school leaders or municipal councillors to set goals for local job creation and social assistance goals through the construction projects for which they are applying.    PLA may include provisions relating to targeted recruitment and learning relationships.
