A criminal lawyer has won his application to view confidential documents pertaining to an investigation into alleged police brutality during the G20 summit in Toronto.

Justice Rob Clark ruled Friday that the Special Investigations Unit, Ontario's civilian-run police watchdog, must allow defence lawyer Mike Leitold to review any and all materials regarding a complaint of police brutality lodged by Adam Nobody, who suffered facial fractures after being apprehended by a group of officers at a protest during the summit on June 26.

The documents have been ordered to be released as sealed evidence to the defence lawyer by the end of January.

Leitold asked to be given access to the material because he says Det.-Const. Luke Watson and Det.-Const.Todd Storey, two Toronto police officers investigated in the Nobody case, also allegedly beat his client, Abbas Jama, 26. Clark said the documents are likely relevant to Leitold's case.

Clark's ruling also applies to any documents prepared by Toronto police in connection to the probe.

As well, any material produced by Watson and Story in connection to to their duties and conduct during the G20 must also be disclosed, Clark said.

Nobody, 27, alleges he was beaten on two separate occasions by police at Queen's Park on June 26.

One scuffle was caught on camera and a Toronto police officer has been charged in connection with that alleged assault. But Nobody says he was then taken to another obscured area and that's where he alleges two undercover police officers — Storey and Watson — continued beating him. The SIU investigated the second incident, but said it did not have any corroborating evidence and did not lay charges.

Leitold alleges Storey and Watson beat his client Jama in a June 2009 arrest. Jama is on trial on weapons offences unrelated to the G20 summit.

Leitold said Tuesday in court the alleged attack on Nobody and the alleged attack on Jama point to "a pattern of police brutality in a strikingly similar method ... and that the documents might show a propensity for violence."

But the Crown and five other lawyers representing the SIU and the Toronto police were opposed to releasing the documents. They say the SIU did not find the officers culpable in any wrongdoing.
