There may be more legal battles over the Manitoba government's sales tax increase.

Opposition Leader Brian Pallister is not ruling out an appeal of last week's court decision that upheld the tax hike.

​Pallister says he hasn't fully read the 15-page ruling or discussed it with his party's lawyer.

The NDP government, meanwhile, says it may ask the court to order Pallister's party to pay some of the $150,000 it spent in legal costs.

Finance Minister Jennifer Howard says the government hired outside lawyers in addition to its own because so much was at stake.

The government hiked the provincial sales tax last year to eight per cent from seven and eliminated a referendum that had been mandatory under the province's balanced budget law.
