A Winnipeg woman has won a legal fight against her brother-in-law over a pair of Jets season tickets they had agreed to share.

In the dispute, believed to be the first involving Jets tickets, Darlene Gibb and John Longstaff both claimed the two seats were theirs, based on a verbal agreement they had made with each other.

However, both family members had different versions of how the agreement would work.

Manitoba Court of Queen's Bench Justice Morris Kaufman sided with Gibb on Wednesday, saying she had a formal contract to back her up, not just a casual arrangement between family members.

"I knew we had a contract and it was just a matter of that being proven, and I feel that that's what the judge agreed with," Gibb told reporters outside court.

Court heard that Longstaff was a Manitoba Moose season ticket holder who had an early opportunity to buy Winnipeg Jets seats when the NHL franchise came back to town in 2011. He formed an agreement with Gibb at that time to buy the seats.

Gibb argued that as part of the agreement, Longstaff would have the seats for the 2011-12 season, but he had promised to give them to her this season.

Longstaff, however, claimed that the season tickets were not supposed to be turned over to Gibb until after he died.

Kaufman did not believe Longstaff's argument, stating in court, "How he thought this evidence would fly on the stand is beyond me."

'We were telling the truth'

Gibb said she's thrilled to be finally getting the tickets, and she feels justice has been done in this case.

"I feel very badly that we had to come to court," she said.

"We were telling the truth, so it was sort of hard to try and deal with the other side."

The judge ruled that Longstaff is still entitled to 12 game tickets a season, so it will be up to lawyers to decide who gets tickets to which games, including Friday night's match against the Pittsburgh Penguins.

Officials with True North Sports and Entertainment, which owns the Winnipeg Jets, estimate that 700 people have transferred ownership of season tickets, but this is the only case they know of that has ended up in court.

A True North spokesman said all of the Jets' home games have been sold out since the franchise returned to Winnipeg, and there are still more than 8,000 people on the waiting list.

Local lawyers recommend that Jets fans who share their season tickets should sign contracts to avoid any confusion.
