Federal counsel Ashraf Hamid said the appeal was filed on Wednesday.

Rosmah, the wife of former prime minister Najib Razak, was allowed to appoint the expert to identify and verify four of the 44 items of jewellery seized by police during a raid last year.

Judge Wong Chee Lin allowed the application on Sept 17, subject to the consent of Bank Negara Malaysia due to security issues as the jewellery is being kept in a vault.

Rosmah’s lawyer Rajivan Nambiar said Wong had fixed Oct 16 to hear his client’s application to postpone the trial since the government has filed the appeal.

“The trial scheduled between Oct 21 and Oct 24 cannot possibly go on as our expert cannot do the inspection,” he told reporters after case management in chambers today.

The suit in questioned was filed by Lebanese jeweller Global Royalty Trading SAL which claimed to have sent 44 pieces of jewellery, each worth between US$124,000 (RM519,183) and US$925,000 (RM3.8 million), to Rosmah through a courier and two of its agents on Feb 10, 2018.

The company said Rosmah had confirmed and accepted its terms and conditions.

It also claimed that Rosmah, in a letter dated May 22, 2018, confirmed and acknowledged receiving the jewellery but said the items were no longer in her possession as they had been confiscated by the Malaysian authorities.

Global Royalty is seeking a court declaration that it owns the jewellery and that ownership of the items was not transferred to Rosmah.

It is also seeking a mandatory order for Rosmah to provide a list of the jewellery seized for them to be returned, or for her to pay US$14.79 million as the price of the jewellery.

Lawyer David Gurupatham, who is representing the jeweller, said his client has also deposited RM75,000 in court as security for costs as demanded by Rosmah.

She had wanted the money placed beforehand to be paid as costs to her should the court dismiss the jeweller’s suit.
