Weir faces a reconvened show cause hearing at Racing Victoria on Monday to determine whether he will be allowed to continue training ahead of charges levelled against him being heard by the Racing Appeals and Disciplinary Board.
As it stands, with Weir's assistant Jarrod McLean - also a licensed trainer - set to fight his charge relating to possession of a jigger, McLean is able to continue on training in the interim, although the stewards declared he cannot receive horses that were in the possession of Weir.
"This is a complex matter and the stewards were determined to be thorough and give due consideration to the submissions made, their legal advice and the ongoing investigations, " Racing Victoria executive general manager Jamie Stier said.
"He has advised the stewards that he will not contest those charges which have drawn considerable negative publicity to the sport", Mr Stier said.
Darren Weir faces a four-year ban from racing after opting not to contest charges relating to possesiong of "jiggers" which were uncovered in a raid of his stables.
Weir must divest himself of any registered ownership interest in a registered horse, prior to that horse being permitted to accept for any race. Any horses trained by him that have accepted to race will be withdrawn by order of the stewards.
"If a horse is pushing itself to the absolute limit because it knows it's going to get a taser up the date because of people like Darren weir and the freaks he works with - if Racing Victoria thinks four years is an adequate penalty they have got rocks in their head".
On Friday, RV stewards issued six charges against Weir, four against McLean four and two against foreperson Tyson Kermond.
"The stewards note that investigations remain ongoing and that they reserve the right to act upon any new evidence that comes to hand during the course of those investigations".
