Clubs usually have until 11am on Tuesday to inform the AFL if they plan to contest a charge laid by the panel, but given the number of charges laid against Baker the Saints requested - and received - permission to lodge their official position no later than 12:30pm.
Baker faces up to 12 weeks on the sidelines if St Kilda unsuccessfully contests the four charges laid against him - three for striking and one for misconduct - after clashes with Geelong's Steven Johnson last Friday night.
He can receive a nine-week ban with an early guilty to plea on all four counts.
Johnson is facing a four-week suspension relating to two striking charges - against Baker - which can be cut to three weeks with an early guilty plea.
Cat Cam Mooney was also cited from the mach that saw the Geelong defeated by 24 points.
Mooney, who has also run foul of the tribunal in recent years, can have a three-week ban cut to two should he plead guilty to striking Saint Jason Blake.
