I'm here but very busy with some family matters.
If you're referring to the BOOTLEG SERIES issues, Dylan's people are closely involved. Sometimes they conceive the project, research it, decide the content and so on, handing it over to Sony Legacy to master etc . That's my understanding. For example, the decision to "construct" a Rolling Thunder concert for BOOTLEG SERIES VOL.5 was made by Dylan's people, not by the record comapny. I have no doubt that there was a certain amount of discussion about this and other releases in the series but it was, in effect, a "Dylan" decision, not a Sony decision. I don't know just how much Dylan is involved. I'm sure he has to OK such a release but the official line seems to be that he doesn't pay very much attention to such things. My guess is that he does - but maybe less than Neil Young does to his archive releases - as I can't imagine he allows anything this major to be released in his name without a say-so.
That said, Sony seem to be able to undertake re-relelases and compilations of already released material without direct involvement from Dylan's people. For example, the 3-CD "DYLAN" release of a few years ago (the one in the red box set, thought there were jewel case versions) was entirely the responsibility of Sony UK, who conceived it, put it together and marketed it. Of course, there was involvement from Dylan's office (as in the agrrement for the re-working of one old track by Mark Ronson for a video in support of the release) but rumour had it that they had to delay a project they had in mind because of it. There was scepticism that the "DYLAN" box set would do well but, in point of fact, it sold surprisingly well, such that Sony tried something similar with a later Dylan relelase, with a hefty price tag for the De Luxe version. There was an outcry from Dylan fans, at which point the unofficial word from Dylan's office was that pricing was a record comapny matter and that it would not be permitted to happen again.
