Anglicanorum Coetibus and CCEO Canon 35

In 2009, Pope Benedict XVI revolutionized the Church's landscape with the promulgation of the apostolic constitution Anglicanorum coetibus, radically altering ecumenical dialogue and creating a new canonical structure (a Personal Ordinariate) to welcome former Anglicans into the Catholic Church, while maintaining essential elements of Anglican patrimony. One year after the erection of the Ordinariate of the Chair of St Peter in the USA, in a letter dated February 13, 2013, then-Ordinary, Msgr. Jeffery N. Steensen posed a series of questions regarding the established regulations governing membership in the Personal Ordinariate. In response to these questions, the Holy Father approved modifications that allow the Ordinariate to expand its exercise of the evangelical mandate of the Christ. These modifications could be considered as an example of the "particular law" foreseen by CCEO canon 35 and applied to the mission of the Eastern Catholic Churches outside their historical territory.
