The Holy See announced Dec. 22, shortly after Boeselager's dismissal, that Pope Francis had formed a group to investigate the matter.
On Jan. 10 the Knights issued a statement defending their decision, calling Boeselager's dismissal "an internal act of governance," making the group established by the Holy See to investigate the decision "legally irrelevant" given the Order's sovereignty.
The Holy See, in turn, reiterated Jan. 17 its confidence in its investigative group and indicated it was awaiting the group's report "in order to adopt, within its area of competence, the most fitting decisions for the good of the Sovereign Military Order of Malta and of the Church."
The Order of Malta is a chivalric order which was founded in 1099, originally to provide protection and medical care to Holy Land pilgrims. It now performs humanitarian work throughout the world, and its two principle missions are defense of the faith and care for the poor.
It maintains sovereignty, holding diplomatic relations with more than 100 states and United Nations permanent observer status.
Festing had been elected Prince and Grand Master of the Order of Malta March 11, 2008.
He was born in Northumberland in the United Kingdom in 1949 and as a child lived for a period of time in both Egypt and Singapore where his father, Field Marshal Sir Francis Festing, Chief of the Imperial General Staff, was posted.
The former Grand Master studied history at Ampleforth and St. John's College Cambridge. Also an art expert, he has spent the majority of his professional career working at an international art auction house.
Festing served in the Grenadier Guards and still holds the rank of colonel in the Territorial Army. He was also appointed by the Queen as an Officer of the Order of the British Empire (OBE), a role in which he served as one of her deputy lieutenants in the country of Northumberland.
Officially becoming a member of the Order of Malta in 1977, Festing took solemn religious vows in 1991, becoming a professed knight. In 1993 he became the Grand Prior of England, a position he held until 2008.
In this role, Festing led humanitarian aid missions in several countries, including Kosovo, Serbia and Croatia, and was head of the British delegation during the Orders' annual international pilgrimage to Lourdes.

In addition to his other roles, Festing has been made an honorary citizen of the cities of Rapallo and Pompeii in Italy, and Birgu in Malta. He was also awarded honorary degrees by the Catholic University of America, the Northumbria University, John Cabot University, the Fu Jen Catholic University of Taiwan and the Catholic University Santa Maria La Antigua of Panama.
