A bankruptcy trustee who controls 7 percent of the Sacramento Kings says the team’s limited partners are being denied their legal right to match a Seattle investment group’s purchase offer for the team.

The assertion by trustee David Flemmer could present a major legal challenge to the Maloof family as it attempts to complete its just-announced sale of the team to a group that intends to move it to Seattle.

Flemmer, the court-appointed trustee overseeing the 7 percent share of the Kings owned by team limited partner Bob Cook, said Cook and other minority owners have “first right of refusal” to buy the club. He said that right is guaranteed in the partnership agreements governing ownership of the team.
