A federal appeals court in New York City has thrown out a decision that barred Congress from withholding funds from the activist group ACORN.

The ruling Friday reverses a decision by a district court. That judge found Congress had violated ACORN's rights by punishing it without a trial.

ACORN describes itself as an advocate for low-income and minority home buyers and residents.

Critics say the group has engaged in voter registration fraud and embezzlement. They say it has violated the tax-exempt status of some of its affiliates by engaging in partisan political activities.

ACORN's full name is the Association of Community Organizations for Reform Now.
