A Baltimore City Circuit Court judge yesterday certified as a class action a lawsuit against the city's cable television franchise that contends that the company's late-payment fees are a ruse to charge more for cable than regulations allow.
Three plaintiffs represented by Washington attorney Philip S. Friedman said TCI Communications of Baltimore charges a $5 late fee if payment is not received within about 10 days of billing. Now that Circuit Judge Gary I. Strausberg has certified the lawsuit as a class action, all subscribers who have paid a late fee since November 1991 are plaintiffs in the suit.
