Veterans Appeals Improvement and Modernization Act of 2009 - Provides that if a veteran claimant submits evidence in support of a case for which a substantive appeal has been filed to the Board of Veterans' Appeals, such evidence shall be submitted directly to the Board and not to a regional office of the Department of Veterans Affairs (VA), unless the claimant requests that the evidence first be reviewed by the regional office.
Empowers the Court of Appeals for Veterans Claims to affirm, modify, reverse, remand, or vacate and remand a decision of the Board after deciding all relevant assignments of error raised on appeal. Provides that whenever the Court reverses a decision on the merits of a particular claim and orders an award of benefits, the Court need not decide any additional assignments of error relating to that claim.
Establishes the Veterans Judicial Review Commission to evaluate and make specific decisions to improve the administrative and judicial appellate review processes of veterans' and survivors' benefits determinations.
