Corby contests drugs conviction

Corby says her luggage was tampered with

Lawyers for Schapelle Corby, the Australian woman sentenced to 20 years in a Bali jail for drug smuggling, have appealed against her conviction.

The move came one day after prosecution lawyers also lodged an appeal, arguing that her sentence should be increased to life imprisonment.

Corby, 27, claimed the 4.1kg (9lbs) of marijuana found in her bag was planted by Australian baggage handlers.

Some Australians said they would not visit Bali in protest at her jailing.

Corby's defence lawyers want to introduce new witnesses, including check-in staff in Australia and prison inmates in Victoria. A witness at Corby's trial said he had overheard the inmates joking that the drugs found in her boogie board bag had been put there by Australian baggage handlers.

Lawyers also want to present airport close circuit TV footage.

Schapelle is very tense - easy to get excited, easy to get sad Lily Lubis, lawyer

The appeal will be heard by three High Court judges, who will have 60 days to hand down a decision, but could take an additional 30 days to consider it.

But prosecutor Ida Bagus Wiswantanu said he wanted her sentence increased to life in prison.

"In our appeal, we stressed the negative effects of the influence of marijuana and similar illegal drugs on the youth of the nation," he said.

One of Corby's lawyers said her client was extremely stressed as a result of the appeals.

"Schapelle is very tense - easy to get excited, easy to get sad. She is very sensitive and I don't want to add to her burdens, so I just try to give her the confidence not to lose hope," said Lily Lubis.

Corby's case has stirred widespread public sympathy in Australia and there have been several cases of white powder - later determined to be harmless - sent to institutions in Canberra amid the emotional backlash.

Part of parliament house was closed down on Tuesday after it received a package of powder, but reopened once it was established the substance was harmless.

Corby is being held in Bali's Kerobokan Prison, but Indonesia and Australia are currently negotiating the possibility that Corby serve her sentence in her home country.
