Omar Khadr's lawyer says the Conservative government is pursuing a case against his client that they know is "fiction."

Last week, an Alberta judge granted Khadr bail. Within minutes of Friday's decision, the Conservative government said it would appeal the decision affecting the "convicted terrorist."

Khadr's lawyer, Dennis Edney, told CTV's Question Period that Prime Minister Stephen Harper and Public Safety Minister Steven Blaney are pursuing a case they know they know is "fiction."

"It's fascinating what they say -- Blaney says, Harper says -- because the truth of the matter is they're lying and they know they're lying," said Edney.

“Canada should never have allowed Omar Khadr to be locked away in Guantanamo. Every other western country requested and were granted return of their returnees. The second part of that fiction that they create is that they know that there's no evidence to tie Omar Khadr to having thrown a hand grenade."

Khadr is currently serving an eight-year sentence handed down by a U.S. military commission in 2010. He's accused of killing an American soldier in 2002, but his lawyer argues he was a child soldier at the time. The Canadian citizen was held in Guantanamo Bay Prison until 2012, when he was transferred to a prison in Alberta.

Edney says he is impressed with the government's perseverance in their case against Khadr.

"The rule of law means nothing to this government. And within about five or 10 minutes of the ruling coming out, they obviously took no time to read the decision and immediately said they're appealing. And they're appealing on the backs of the taxpayer," he said.

Edney called on the government to allow Canadian media outlets to interview Khadr, "so the Canadian public can see who this kid is."

A federal judge recently rejected a request from the Toronto Star and CBC to interview Khadr, agreeing with the warden at the Alberta prison where Khadr is being held that an interview would pose a security risk.

To Edney, Khadr is a model prisoner who poses no threat to the community. That's why he and his family, who have followed the Khadr case for 11 years, have agreed to house him when he's released on bail.

"He's welcome in my house. He'll be a part of the family. He'll come into the house. He'll continue his education. He'll probably have to get a part time job. He'll be like any guest that comes to stay."

Having been in prison since the age of 15, Edney said Khadr will have a lot of adjusting to do when he enters the real world. For instance, Edney said his wife Patricia intends to teach Khadr how to cook.

But Edney said Khadr has some obstacles ahead of him before he can think about his release. Khadr will be back in court on May 5, when bail conditions will be set. But Edney said the government's intentions to appeal will not affect his client's release.

"This government has to show the court that it has a meritorious claim for an appeal and we will meeting them in court and we will be challenging that. And so there's a bit of a journey to go on."

Edney said Khadr is still cautiously optimistic about his case. He spoke to him by phone on Friday following the judge's decision.

"He's been here before. We have been successful so many times and he's still in jail. So I think he's saying to himself … I'll wait and see."
