Subway's tuna sandwiches have come under intense scrutiny. Jörg Carstensen/Getty Images A lawsuit alleging that Subway mislabeled its tuna has been dismissed by a judge, per reports. A California court found the claimants did not meet a legal standard to sue the sandwich giant. Subway called the suit, which was filed earlier this year, "reckless and improper." A federal judge in California dismissed a case against Subway on Thursday, which had been brought by consumers who alleged that the tuna used in its sandwiches was not authentic.
