A Kenyan appeals court has lifted a suspension placed on a disputed government finance law that will double the value-added tax on fuel and introduce a new housing levy.

The legislation sparked deadly opposition protests this month.

Under the new law, the value added tax on fuel will double to 16% and workers will also face a 1.5% housing levy that will be matched by employers.

The case challenging the finance law was first brought to court by an opposition senator seeking a declaration that certain parts of the measure should be stopped on grounds that they are unconstitutional.

"Public interest tilts in favour of setting aside the conservatory orders by the trial judge," the appeals judges said in their ruling on Friday.

President William Ruto's government says the higher taxes are necessary to stabilise government finances, which have been strained by growing debt repayments and lower-than-expected growth in tax collection.

In response to the law's signing, the opposition coalition has held five protests this month, some of which descended into violent confrontations wit h police where more than two dozen people were killed and scores injured.
