OK although this isn't directly related to election reform, the fact that the contesting of the Ohio electorate after the 2004 election was dismissed and the attorney's who contested were threatened with sanctions (later dismissed), it does apply:
Campaign Cash Mirrors a High Court's Rulings

Columbus, Ohio - In the fall of 2004, Terrence O'Donnell, an affable judge with the placid good looks of a small-market news anchor, was running hard to keep his seat on the Ohio Supreme Court. He was also considering two important class-action lawsuits that had been argued many months before.
In the weeks before the election, Justice O'Donnell's campaign accepted thousands of dollars from the political action committees of three companies that were defendants in the suits. Two of the cases dealt with defective cars, and one involved a toxic substance. Weeks after winning his race, Justice O'Donnell joined majorities that handed the three companies significant victories.
Justice O'Donnell's conduct was unexceptional. In one of the cases, every justice in the 4-to-3 majority had taken money from affiliates of the companies. None of the dissenters had done so, but they had accepted contributions from lawyers for the plaintiffs.

An examination of the Ohio Supreme Court by The New York Times found that its justices routinely sat on cases after receiving campaign contributions from the parties involved or from groups that filed supporting briefs. On average, they voted in favor of contributors 70 percent of the time. Justice O'Donnell voted for his contributors 91 percent of the time, the highest rate of any justice on the court.
