Madonna will not be allowed to adopt a second child from Malawi, a four-year-old girl named Mercy James, the African country's High Court ruled yesterday.

The ruling will please campaigners who say authorities have given the pop star special treatment. Malawi's government, which came under fire after Madonna adopted a 13-month-old Malawian boy, had said on Thursday it would support a second adoption.

Court registrar Ken Manda told reporters the American singer's bid to adopt Mercy had been rejected because she was not a resident of Malawi.

An AIDS epidemic in the impoverished southern African country has orphaned more than one million children and Madonna has set up a charity for Malawian children.

Her lawyer, Alan Chinula, said he had lodged an appeal over the ruling with the Supreme Court.

"I just filed the notice of appeal this afternoon on instructions from my client," Mr Chinula said.

"I'm currently studying the judgment so that I can come up with the grounds to appeal."

In her ruling, Judge Esimie Chombo warned against celebrity adoptions because they could lead to child trafficking.

"Anyone could come to Malawi and quickly arrange for an adoption that might have grave consequences on the very children that the law seeks to protect," she said.

Malawian rights groups, who accused the government of skirting residency laws when Madonna adopted David Banda in 2006, also opposed the latest adoption attempt.
