(Brotherhood of Maintenance of Way Employes PARTIES TO DISPUTE:


STATEMENT OF CLAIM :













FINDINGS :

The Third Division of the Adjustment Board, upon the whole record and all the evidence, finds that:

The carrier or carriers and the employee or employees involved in this dispute are respectively carrier and employee within the meaning of the Railway Labor Act, as approved June 21, 1934.

This Division of the Adjustment Board has jurisdiction over the dispute involved herein.


Form 1 Award No. 35301

The claim seeks payment of a mobile crew expense reimbursement per diem in the amount of $41.00 for each day worked by the Claimants during the period of April 8 through April 30, 1996.





As agreed by the parties on October 3,1994, the applicable mobile crew expense reimbursement per diem is $41.00.


The Claimants are seasonal employees headquartered in Billings, Montana, and assigned to Gang 1957. The Organization asserts that the Claimants were required to travel in excess of 40 miles between the West Switch at Columbus, Montana, and Billings and thus are entitled to the claimed per diem.

      And finally, according to the Organization:


      "Employes from the Columbus area have always been paid the applicable per diem since the agreement was effective. The Company has always recognized the distance to be 40 or more miles. When employes are reimbursed for mileage from Columbus to Billings, they are reimbursed at the rate of 42 miles one way or 84 miles round trip. The Company recognizes the distance to be more than 40 miles. When you review an Official State Highway Map, the distance is more than 40 miles. The State Highway Department recognizes the distance to be more than 40 miles. For all these years, from all of these sources, they can't all be wrong. All of them have recognized the distance to be in excess of 40 miles.


      That State has not `shrunk,' the distance remains more than 40 miles . . . ."


For the sake of discussion, we will agree with the Carrier that the exact measuring tool is open to debate and is "unclear in the Agreement." However, a fundamental Rule of contract construction is to look to past practice in order to attempt to ascertain the meaning of unclear language.


Here, there is a demonstrated past practice. The Organization has shown that in the past employees have been paid on the basis of a computed distance in excess of 40 miles. The Carrier effectively admits to the existence of that practice. According to the Carrier, ". . . you are correct that it had been paid in some instances . . . ." The Carrier cannot now negate the existence of that past practice by now taking the position that "it was paid in error" or that "it was paid by mistake." The demonstrated fact is that, in the past, it was paid.


The demonstrated past practice resolves the alleged ambiguity. The mobile crew expense reimbursement per diem should have been paid. The claim will be sustained.


                        AWARD


      Claim sustained.
