Langer only infrequently won cases in her 23-year career. In 1977, she lost her licence to defend Israeli conscientious objectors before Israeli courts and could be excluded from proceedings at any time on security grounds. Langer counted her successful defense in 1979 of Nablus mayor Bassam Shaka as the high point of her career. Shaka had been a PLO supporter and outspoken critic of the Camp David accords, and was subsequently accused of inciting terrorism by his public statements and issued an expulsion order. Langer defended him successfully, having the expulsion order overturned by the Israeli supreme court. For many years Langer was vice president of the Israeli League for Human and Civil Rights.
