EXCEPTIONS TO ARBITRATION AWARDS Either party to grievance arbitration may file with the Authority an exception (or appeal) to an arbitrator's award issued after the arbitration. The Authority will review an arbitrator's award to which an exception has been filed to determine if the award is deficient * because it is contrary to any law, rule or regulation; or * on the grounds similar to those applied by Federal courts in private sector labor-management relations. Certain awards are not reviewable by the Authority. These include: * an action based on unacceptable performance covered by 5 USC 4303; * a removal, suspension for more than 14 days, reduction in grade, reduction in pay, or furlough of 30 days or less covered by 5 USC 7512; * matters similar to those covered under 5USC <185> 4303 and 5 USC Ch. 75, subch. II, which arise under other personnel systems. An exception to an arbitrator's award must be filed with the Authority's national office in Washington, D.C. The time limit for filing is 30 days beginning on the date the award is served on the filing party.
