Hungary's consul-general may seek diplomatic immunity to avoid a potentially embarrassing legal clash after conciliation talks with a pregnant maid over her alleged unfair dismissal broke down yesterday. Ninety minutes of discussions between Laszlo Vizi, his wife Katalin, their domestic helper Nanette Cajayon and a Labour Department arbitrator failed to find common ground. The dispute now looks likely to take a legal twist as Mrs Cajayon, who says Budapest's envoy wants to terminate her contract because she is pregnant, intends to file for a Labour Tribunal hearing. Mr Vizi says she is being sacked because of her poor performance and unreliability, not because of her pregnancy. The Labour Department last night confirmed the matter had been transferred to the tribunal. After yesterday's talks collapsed, Mrs Cajayon, 40, whose husband works in Hong Kong as a driver, said that during talks at the department's offices in Western Court, Mr Vizi, 43, raised the issue of diplomatic immunity. 'The [Labour Department] officer said she didn't know if it [diplomatic immunity] applied in this case and it would have to be looked into. 'We couldn't agree on anything. He offered to pay me $7,680 but that is not enough,' said Mrs Cajayon. Mr Vizi and his wife left the meeting via a back stairway and side door to avoid questions, but when the South China Morning Post spoke to him later and asked if he would be invoking diplomatic immunity, he said: 'That is a hypothetical question which I am not prepared to answer.' However, a source confirmed to the Post that the immunity angle had been raised by Mr Vizi. The Protocol Division last night refused to comment on whether it had been contacted by Mr Vizi. If the Hungarian diplomat invoked diplomatic immunity he would be the second consul-general known to have done so in the SAR this year. Last month, Vietnam's top diplomat in the territory, Nguyen Viet Hung, was told he would not face prosecution when he invoked diplomatic immunity after police picked him up for allegedly groping a woman in Causeway Bay. Under the Vienna Convention, diplomatic immunity will normally only be turned down in Hong Kong if the incident is considered a grave crime, meaning if it carries a punishment of five or more years' imprisonment. Mrs Cajayon - who is seven months' pregnant - is claiming $53,000, saying she is due wages, extra payments for food, accommodation and travel, and maternity compensation. She also claims she had to sign two contracts, one for the Immigration Department to get a work visa and another for the Hungarian Consulate. She says she had to work in Mr Vizi's home and in his office, in breach of the law. 'I started at 9am in the office, then for an hour, sometimes more if there were guests, served tea or coffee and then cleaned up before going back to his apartment,' she said. Mr Vizi denies this but admits she may have 'washed some cups'.
