If Section 31 is so "official" and not rogue, why in Inter Arma Enim Silent Leges does Ross insist of taking off the comm badges and talking S31 talk to Bashir "off the record"? That's a long way down from Tyler gleefully sporting and using his S31 comm badge.Probably because the ORIGINAL Starfleet Charter was pre-Federation. That said, Sloan also sates:
SLOAN: Let's just say I belong to another branch of Starfleet Intelligence. Our official designation is Section thirty one.
^^^
Which is the CURRENT Federation Starfleet.
And before you gop claiming that somehow the currnt Federation Starfleet must not condone or know about current version of Section 31 or condone it, there's the DS9 eopisodes:
"Inter Arma Enim Silent Leges"
Where Admiral Ross is working directly with Sloan and they are BOTH using Bashir to assist (unknowingly until the end) with the elevation of a pro-Federation Romulan to a council, and the ultimate elimination of an anti-Federation Romulan which they believe will be executed as a traitor/collaborator.
and
"Extreme Measures"
Where Bashir discovers Section 31's plans for Founder Genocide, and that he was an unwitting part if it and 73 people must have been involved - and then p[roceeds to luyre Slaon to Ds9 with news that he has a cure...
But my point? Ds9 cleartly shows that Section 31 is indeed an arm of the current Federation Starfleet; and it's actions are known and supported BY high ranking members of Starfleet.
There's nothing 'Rogue' about it.
So Admiral Ross and other high ranking people work for Section 31. Does that mean that Section 31 officially works for the Federation? If that were evidence, then the Khitomer conspiracy must also have been officially affiliated with the Federation since Admiral Cartwright and his buddies were involved!
I missed that line about Sloan, but all I'll concede is that he is saying contradictory things. (It happens in Star Trek).
So there's leeway for both interpretations, but honestly when a Star Trek writer and showrunner outright says S31 is unofficial in the 24th century and he's working on an entire prequel series detailing it, I know which interpretation I'm siding with.
