SACRAMENTO, CALIF. ? Al Davis and his Oakland Raiders were awarded $34.2 million Tuesday by a jury that found Oakland coliseum officials failed to deliver on promises of sold-out stadiums in luring the team back from Los Angeles.

The verdict in the lawsuit was far less than the $570 million to $833 million the Raiders sought to compensate for weak ticket sales and the declining value of the franchise.

Both sides promised to appeal the verdict — reached after more than 10 days of deliberations. The jury heard nearly four months of testimony from 45 witnesses and had more than 600 pieces of evidence to consider.

“Do we think that there’s adequate compensation for damages? No,” said the Raiders’ attorney, Roger Dreyer. “We’re disappointed with the verdict. We’re disappointed with the numbers.”

The case dates to 1995 when Davis, the legendary Raiders owner, maneuvered to get his team out of Southern California after revenues waned, the team’s stadium was shaken by an earthquake and a deal collapsed to build a new stadium.

The deal gave the Raiders a $53 million loan, $10 million for a training complex and $100 million to renovate the coliseum, which is shared with the Oakland Athletics.

Oakland-Alameda County Coliseum, its chief negotiator Ed DeSilva and the now-defunct Arthur Andersen accounting firm were accused of intentionally misleading the team with its promises of sold-out games.

The jury ruled the coliseum acted negligently, but said none of the defendants intentionally misrepresented ticket sales.

The coliseum’s lawyer said any box-office flop should be partly blamed on high ticket prices and the Raiders’ poor performance on the field upon their return to Oakland.

The Raiders are one of the most storied franchises in the NFL, from their days as an AFL power in the 1960s to their return to dominance in the last three years.
