A developer promising a multi-billion dollar makeover for impoverished north St. Louis won a legal battle Tuesday as the Missouri Supreme Court rejected a challenge to a state law directing tens of millions of dollars of tax credits toward his project.

The seven-member Supreme Court was divided in its reasoning but united in the ultimate result of its ruling, which secures state financing for the developer to assemble and maintain large swaths of land. Eventually, Paul McKee's NorthSide Regeneration LLC wants to build 10,000 homes and millions of square feet of office space in a two-square-mile area north of downtown St. Louis.

A lawsuit by two local residents took issue with a 2007 state law enacted with McKee's project in mind. That law authorizes up to $95 million of tax credits to offset part of the cost of buying and maintaining large amounts of property in impoverished areas. NorthSide Regeneration so far has received about $28 million in tax credits.

Tax credits reduce the amount of state income tax owed by a taxpayer. The lawsuit claimed the credits were similar to getting cash from the state and thus violated the Missouri Constitution by granting public money to a private person or corporation. A Cole County judge ruled against the plaintiffs in March 2010 and the case was appealed to the state Supreme Court.

Workers who filed a class-action lawsuit against a Kansas slaughterhouse for unpaid wages and overtime have asked a federal judge to bar Creekstone Farms Premium Beef from discovering their immigration status during the litigation.

The employees have asked U.S. District Judge Eric Melgren for a protective order prohibiting the Arkansas City meatpacker from receiving from the named plaintiffs — or any other workers who opt into the lawsuit — any information pertaining to their present names or any other names they may have used.

They also seek to avoid having to disclose their place of birth, Social Security number and any present or prior addresses. The plaintiff's motion also seeks an order protecting the workers from having to turn over to Creekstone Farms any tax returns or any other tax forms filed under any of their identities or having to disclose the dates and times of entry into the United States. They also want to avoid turning over all identification documents likely to lead to the discovery of their immigration status.

Their attorney, Mark Kistler, told The Associated Press Tuesday that the courts already have decided that these types of information which could lead to discovery of immigration status should be protected from discovery during a lawsuit.

A federal appeals court ruling could lead to even more spending in Wisconsin's recall elections.

A 7th U.S. Circuit Court of Appeals panel ruled Monday that the state's $10,000 annual contribution limit on so-called "super PACs," or political action committees that do not coordinate with specific candidates or their campaigns, can't be enforced while a lawsuit from one of the groups is pending.

The lawsuit was brought by Wisconsin Right to Life's political action committee, and the group's attorney said it will immediately begin soliciting big-dollar donations to spend in the recalls targeting six Republicans and two Democrats.

"They will raise money in excess of the limits," said Right to Life attorney James Bopp, Jr.

To date, Wisconsin Right to Life's PAC reported spending only $325 on telephone calls in support of Republican Sen. Randy Hopper and against his Democratic challenger, Jessica King.

The appeals court said the donation limit can be exceeded while the underlying lawsuit is pending. Wisconsin Right to Life argues that the limits are an unconstitutional restriction on free speech.

Oral arguments were tentatively planned for September, after both the Aug. 9 elections targeting six Republican state senators and elections a week later involving two Democratic incumbents.
