The lack of canonical protections for 3GF/M's has been one of the most important problems highlighted by LARC since its inception. Now we have an important acknowledgement of that problem from the Papal Delegate himself. (For now, we're reduced to a Googelle translation -- help appreciated!)
Although Archbishop de Paolis Velasio tried to comfort the remaining 3gf's with white lies when a large group of their number 3GF departed to created Totus Tuus (which does exist canonically), despite everything, the "consecrated" members of the Movement founded by Marcial Maciel STILL DO NOT EXIST canonically.
This fact is recognized in an official text approved on 19 March and published on its website . They quote: "(...) the Cardinal did see that it was not possible to sign an agreement with legal force until the consecrated branches were canonically erected associations branches recognised by the Holy See."
When the so-called Consecrated 3GF were sent home without any formalities, there was much discussion about the legal inconsistencies within the Movement. Trying to contain damage , the papal delegate said that they "could" dismiss a member without authorization ... the fact is that Legionaries being religious of pontifical right  require authorization from the Holy See, while the so-called Consecrated (3GM and 3GF) do not require his authorization nor that of the [directress?] ... i.e. the member can withdraw any time they want since they have no juridical tie.
Concerning God, any priest with legitimate falculties could dissolve the sincere act of consecration in the internal forum. This detail is important because 3GF/M's believe that leaving behind their consecration to God is somehow a betrayal.
Many 3GM and 3GF -- following the typical behavioral patterns when questioned about it -- will tell you that they were not fooled and delivered their promisesin freedom. But the fact is that none of those promises have been [binding?] because as of March 2014, the Institute that would be canonically recognized by the Church as still never been erected!
The same formula of consecration involves a deception since there is canonically the Institute which is being devoted, as recently recognized the 3GM and 3GF in document on 19 March. Consecration does exist, because it comes from the heart and who receives God as He scrutinizes within each consciousness.
Does this mean that any 3GF or 3GM can go to any priest with faculties to confess and ask for exemption of consecration? So, as already said in several widely Blogs Internet commenting Canon Law. One could argue that the promises were issued publicly, but this does not mean its strictly private, because legally there is no institution in which promises are made public.
Moreover, the document entitled "Interim Framework for collaboration in the mission of RC general and territorial level" is just a text bureaucratic organization. Starts very arty with a section devoted to "Groundwork Charismatic", but did not speak any charisma or any foundation. As Legionaries, as if by dint of repeating manage convinced of the existence of a charism.
