A lawyer is appealing a decision to temporarily remove him as trustee of a First Nation's account in northern Alberta.

The chief of the Tallcree First Nation is suing Jeff Rath over how he managed the First Nation's trust account.

The First Nation and Rath have been in a legal battle for years.

The First Nation got over $50 million from the government and hired Rath to manage the money.

The chief says Rath took millions of dollars, but Rath says this is not true.

In June, a judge ordered Rath's company to stop being the trustee.

An Alberta judge froze Jeffrey Rath's accounts related to his legal work.

Rath appealed the decision on July 24.

Rath says the court didn't consider all the facts and made mistakes in its decision.

He says the judge made nine mistakes, including using irrelevant information.

Rath wants the appeals court to cancel the order and stop it until the appeal is decided.

The chief's lawyer says Rath's appeal has no basis and should be dismissed.

The chief will respond strongly to Rath's appeal and ask for costs.
