The D.C. Court of Appeals rejected the request from Roy L. Pearson to overturn a 2007 ruling that denied him damages. Pearson had argued that Custom Cleaners failed to live up to its promise of "Satisfaction Guaranteed."

Three appellate judges agreed Pearson failed to show the store's advertising amounted to fraud and said his argument defied logic.

Pearson can still ask the entire nine-judge appellate court to review the case or appeal to the U.S. Supreme Court.

Pearson did not immediately respond to an e-mail or telephone message seeking comment.

Jin Chung, the dry cleaner owner, said through his lawyer that his family is "very very happy" with the decision. The family said they hope Pearson won't take any further action.

The American Tort Reform Association lauded the court's move, saying the city's easily exploited consumer protection law should be reformed.

The case has taken its toll on both sides. The Chungs have sold the dry cleaning shop, citing a loss of revenue and the emotional strain of defending the lawsuit. Pearson lost his job when a D.C. commission voted not to reappoint him.

Rezko has been among the Democratic governor's top fundraisers and advisers and can provide prosecutors with a penetrating glimpse into the workings of Blagojevich's inner circle. He was convicted in June of scheming to squeeze companies seeking state business for payoffs.

There were signs that Rezko's relationship with prosecutors had soured in recent weeks. But on Tuesday, both sides agreed to postpone his sentence indefinitely, a sign that prosecutors think their sometimes reluctant witness has more to tell them.

While Rezko squared things with federal prosecutors, attorneys for former Blagojevich campaign chairman Christopher Kelly said he intends to plead guilty to tax charges next month. Among other things, Kelly, a roofing contractor and consultant, is charged with using company funds to pay gambling debts and in at least one case writing the payment off as a business expense.

Kelly could also give the government an inside look at the workings of the Blagojevich administration. But chief defense counsel Michael Monico said Tuesday that "cooperation isn't part of the agreement" under which Kelly will plead guilty.

Sheriff Russ Isham of Marion County declined to release the suspect's name, saying it would jeopardize the integrity of the investigation and the safety of officers still working the case.

"We do believe the person responsible for the bombing is in custody," Deputy District Attorney Courtland Geyer said late Sunday.

The suspect was arrested in Salem, located just south of Woodburn, the small city south of Portland where Friday's bombing occurred.

Officers made the arrest shortly after Sheriff Russ Isham of Marion County released surveillance photos of a "person of interest." Geyer would not say if a tip led to the arrest.

He also wouldn't disclose if the man in the photos, apparently taken with a security camera, is the same person in custody.

Isham would not release the precise location where the arrest took place, and said the suspect's name likely wouldn't be released until Monday afternoon.

"I'm really proud of those who tirelessly worked to get us to this point and am humbled by the community's support," Isham said. "We know there is still a lot of hard work ahead of us, but this development will help bring relief to the local community and the officer's families."
