Going much better than when Ryan Hill had it. Boy Hill needs some of Brock's fence posts  =))

I'd imagine it will be swift. Same old story, double standards

To keep it consistent it needs to drag on for months

Thoroughbred stewards’ inquiry – Trainer Mr Brock Lewthwaite (MARINES CRY)
Racing WA Stewards have concluded an inquiry into reports from ChemCentre in Perth and
Racing Analytical Services Limited (RASL) in Victoria, which detected arsenic above the 0.30
ug/mL threshold in a urine sample taken from MARINES CRY following its win in Race 5 at York
on 2 March 2026.
After hearing evidence from Trainer Mr B Lewthwaite, ChemCentre representative Dr B
Dorakumbura, RWWA Head of Veterinary Services Dr J Medd and RWWA Senior Investigative
Steward Mr P Criddle at the inquiry, Mr Lewthwaite pleaded guilty to the charge of Thoroughbred
Rule of Racing 240 (2), with particulars:
That Mr Lewthwaite, as the licensed trainer, presented MARINES CRY to race in Race 5 at York
on 2 March 2026, where it raced and won, with the prohibited B List substance Arsenic detected
in a post-race urine sample at a concentration exceeding 0.30 milligrams per litre.
Mr Lewthwaite was fined $4000.
Further acting under the provisions of Rule 240 (1), MARINES CRY was disqualified as the
winner of Race 5 at York on 2 March 2026, with placings adjusted and all relevant prizemoney to
be returned and redistributed accordingly.
When determining penalty, Racing WA Stewards considered, among other things:
• Mr Lewthwaite’s plea of guilty and personal circumstances;
• Mr Lewthwaite’s record in relation to prohibited substances;
• That Racing WA Stewards were satisfied that the reported level of Arsenic was likely to
have arisen due to MARINES CRY ingesting CCA treated pine posts at the property;
• The intent and purpose of the Rule 240 (2) which was directed to ensuring a level playing
field and maintaining the necessary confidence of those supporting or involved in the
racing industry, and
• There were no products on Mr Lewthwaite’s training establishment containing Arsenic.
All trainers are again reminded that they should seek to eliminate any access to CCA treated
timbers.
Trainers taking horses to races or trials from yards with known CCA-treated timbers should
inspect fencing and withdraw any horse showing evidence of fresh or ongoing chewing,
regardless of preventative measures.

Moving forward owners should determine if prospective trainers of yearling purchases have CCA treated fence posts, gives them a competitive advantage relative to trainers who dont.
