NSW greyhound report challenged in court

A report which led to the NSW government's ban on greyhound racing contains many statistical errors including on the number of dogs put down, a judge has been told.

David Bennett QC, for the NSW Greyhound Breeders Owners & Trainers Association Limited, briefly outlined their case in the NSW Supreme Court on Tuesday.

The group is seeking a court declaration that the government's June 16 racing inquiry report is invalid.

The Report of the Special Commission of Inquiry into the Greyhound Racing Industry found evidence of systemic animal cruelty in the industry.

In response, NSW Premier Mike Baird announced the industry would be shut down with the ban due to come into effect on July 1 next year.

Mr Bennett submitted that commissioner Michael McHugh's reliance on the concept of "social licence" was unreasonable and outside the terms of reference.

He contended that "statistical errors" had been made in the report, including on the numbers of dogs being put down, and inadmissible evidence had been taken into account, including on the prevalence of live baiting.

The case was adjourned to September 29 for directions.
