Your April 12 editorial "A Good Arbiter" completely ignored the high upfront costs, the heavy anti-consumer bias and the gross procedural disadvantages that characterize private arbitration as opposed to our public courts of law.

These features are why consumer groups, patient advocates, employment rights activists -- essentially everyone besides the corporate lobby -- generally oppose mandatory arbitration of disputes between corporations and regular people.

Arbitration creates grave injustices for the up to 20 percent of American workers who, to keep or get jobs, must waive their constitutional right to take lawbreaking employers to court. If their employer underpays, discriminates against, denies workers' compensation to or otherwise illegally mistreats employees, the employer's handpicked private arbitration company will hear the dispute.

Unlike the measure from Sen. Russell Feingold (D-Wis.), the bill by Sen. Jeff Sessions (R-Ala.) does absolutely nothing for the most financially vulnerable Americans, who in this economy must choose between much-needed employment opportunities and much-cherished constitutional rights. More is at stake here than $200 cellphone contract disputes that can be taken to small-claims court.
