In 2012, the Pennsylvania legislature passed a law requiring everyone to present certain types of photo ID before voting – a requirement that could have disenfranchised many people who cannot obtain ID and created additional burdens that fall heavily on urban, low-income, minority, elderly, and disabled voters. In conjunction with the ACLU of Pennsylvania, the Advancement Project, and Arnold & Porter LLP, the Law Center challenged the photo ID law in Commonwealth Court shortly after it went into effect.
