Cintas Corp., the nation’s largest uniform supplier, went into its annual shareholder meeting on Tuesday armed with a federal judge’s decision rebuffing an attempt to force a revision of its proxy statement.

The statement had been challenged by a trade union that owns “a handful” of shares in the Cincinnati-based company. The union, Unite Here, had argued that the statements were misleading and that further disclosures were necessary in order to alert shareholders to what it called the questionable integrity of the company’s chairman and chief executive, both of whom were up for re-election at the meeting.
