After the territory gained independence as Orange Free State Allison became a member of the Volksraad, government secretary (1862 – 1863) and treasurer, and briefly Acting State President of the Orange Free State in 1863, after President Pretorius had left the State.
The esteem in which his shrewdness in both farming and legal affairs was held led to his election to the Volksraad as member for Wakkerstroom early in the sixties, Marthinus Pretorius being then in his second term of office as president.
