SCHAPELLE Corby looked stunned yesterday when she was told the Australian prisoner who gave evidence in her defence had been attacked in jail.

She was on her way to court in Bali for her latest hearing when she was told rape suspect John Ford had been slashed by another inmate at the prison in Victoria.

Corby was hurried into court to hear prosecutors' reiterate Ford's evidence be cast aside.

They also criticised her defence team, claiming they had employed emotion in their case rather than legal foundation, prompting a nod of agreement from one of the judges.

The prosecution was annoyed the defence had used emotion and "sarcasm" to accuse the prosecutors, police and customs officers of violating the law.

The prosecution said the evidence of customs officer Gusti Nyoman Winata – who claimed Corby tried to stop him looking in her boogie board bag when she was stopped at the airport – was key.

"It's very clear the accused forbid Winata to open the zips further," prosecutor Ni Wayan Sinaryati said.

Prosecutors also argued the failure to fingerprint the vacuum-sealed plastic bag containing the marijuana was not important.

The fact Corby was arrested at the airport with the drugs in her bag was enough to find her guilty, they said.

Ms Sinaryati said Ford's evidence was based entirely on an overheard conversation.

The defence will get the opportunity to respond next Thursday and a verdict is expected about May 26.

But Corby's lawyers said they hoped the Indonesian legal system would realise Ford's evidence was not "a joke" and he came to her defence at great personal risk.

Since the attack, Ford has been held in solitary confinement.

"Finally, this is proof that because of what he did for Schapelle, to give a statement, he got trouble in the jail," Corby's lawyer Lily Lubis said yesterday.

"So I hope the legal system in Indonesia can see that it is not a joke."

Ms Lubis added her client was shaking in her cell.

"Her condition is not good, she is shaking. I never see her like that, she is shaking today, when I touch her hand," she said.

"She's a strong person but lately I feel she has changed a lot.

"She looked more down and this morning I could feel that she was shaking."

She said she hoped Corby would not consider suicide.

"I believe she is a strong person, she will not do a stupid thing like that," she added.

While not conceding defeat, Ms Lubis said they could still appeal to two higher courts.

"This is only the first court. We still have the High Court and the Supreme Court."

Prosecutors have demanded Corby receives a life sentence, not the death penalty.
