The Saskatchewan Court of Appeal has upheld a decision to certify a union at a Wal-Mart store in Weyburn, Sask.

The certification of the United Food and Commercial Workers Local 1400 had originally been issued by the Saskatchewan Labour Board in December 2008.

Wal-Mart had successfully challenged the certification in a lower court but in a recent ruling by Saskatchewan's highest court, that decision was struck down and the union certification was upheld.

The union first applied for certification in 2004. The union says two days ago, a Quebec court upheld an arbitrator's decision that Wal-Mart acted illegally when it shut a store in Jonquiere shortly after workers there formed a union.

The UFCW also has applications pending before the labour board for Wal-Mart stores in Moose Jaw and North Battleford.
