The American Bar Association's policymaking body has once again rejected a proposal to strengthen the bar pass rules that law schools must adhere to in order to remain accredited.

The ABA's House of Delegates voted down the measure Monday during the association's midyear meeting in Las Vegas—just as it did two years ago in Miami. Once again, a cohort of diversity advocates spoke out against the measure, warning that the heightened bar pass standard would disproportionately hurt law schools with high minority enrollment, in turn hobbling longtime efforts to diversify the profession. Delegates debated the measure for less than an hour before voting it down. Only 88 delegates favored the measure while 334 were against it.
