It is, but they're submitting to an independant committee. They should present their case; explain their rules; explain how they believe SFC have broken those rules, and leave them to it.
It's literally the point of using an independant board to determine an outcome to show that no bias or prejudice has been taken into account. Otherwise they'd just do it themselves.
If the EFL have leaned on the board heavily, it's almost akin to influencing a witness.
