Kenya's attorney general says he will appeal against a court decision declaring a form of Islamic courts discriminatory.
On Monday, three judges said "Kadhi" courts favoured Islam over other faiths, and this was unconstitutional since Kenya is a secular country.
The Kadhi courts deal mainly with matters of marriage and inheritance among Kenya's Muslim minority.
They have been a contentious issue as Kenya debates a new constitution.
The country's Attorney General Amos Wako said the judgement itself was unconstitutional and sets a bad precedent.
The Kenyan government - including Mr Wako - supports a draft of the constitution which includes Kadhi courts.
However the Christian churches - which brought the Kadhi case to court six years ago - are opposed to this.
As part of a power-sharing deal to end deadly riots in Kenya following elections in December 2007, it was agreed that a new constitution would be written.
A referendum on the proposed new constitution is due in August.
