KANSAS CITY, KAN. ? The Wyandotte Nation has ended its pursuit of 1,920 acres of land near downtown, saying it won’t appeal a dismissal of its claim.

The American Indian tribe sued for the land in October 2002, citing tribal treaties from the 1800s, but that suit was thrown out by a federal judge last month. David McCullough, the attorney representing the Oklahoma tribe, acknowledged Monday that the chances of successfully advancing the suit were “remote.”

“The lawsuit is over,” he said. “We’ll be looking at whether there is other recourse, besides legal action, against the U.S.”

The announcement was a relief to many here, because the lawsuit clouded owners’ titles to more than 4,000 parcels of land, which the tribe said were valued for tax purposes at $1.9 billion. The land along the Missouri River northeast of downtown comprises much of the city’s Fairfax Industrial District, including the General Motors plant.

Carol Marinovich, mayor of the Unified Government of Wyandotte County and Kansas City, Kan., said the city would consider suing the tribe to recover legal expenses.

U.S. District Judge Carlos Murguia ruled last month that the Wyandotte Nation waited decades too long to file its claim. He said the tribe failed to file with the Indian Claims Commission before the 1951 deadline set by Congress.

The lawsuit was part of the tribe’s nearly decadelong legal struggle to open a casino in Wyandotte County.
