When double line is used it must be used of the actual line to catch the fish. So a leader would begin when the line other then the mainline is attached to the leader(not including backing -which is a totally different topic). having a swivel in the middle of your leader is not against igfa rules. At least not anywhere I have seen.
BTW - if this isn't the case then every single tournament boat I have ever fished on, observed on or even spoke to is breaking the rules. Including quite a few IGFA reps.
