Shareholders of Washington Mutual Inc will have a voice in the company's bankruptcy after a judge refused on Thursday to disband their committee, which Washington Mutual said would complicate the case.

The U.S. Trustee, who plays an oversight role in bankruptcy, appointed the committee earlier this month after being petitioned by 3,500 shareholders. The company immediately asked the court to disband it.

The committee will be able to speak with a unified voice and hire professionals, who would be paid by the company.

Washington Mutual has said since it filed for bankruptcy in 2008 that it is hopelessly insolvent, and therefore there is no need for an official committees of shareholders.
