In 1881 Gladstone was convinced that to pass a Land Bill for Ireland, law and order should be restored. In February 1881 the government therefore passed the Peace Preservation (Ireland) Act 1881 which gave the Viceroy of Ireland powers to suspend habeas corpus, and gave him in effect the power to lock up anyone he liked for as long as he liked. This was the Act used to arrest Irish Nationalist leader Charles Stewart Parnell. In August that year Parliament passed the Land Law (Ireland) Act 1881 which gave Irish tenants "the three Fs"; fair rent, fixity (security) of tenure; and the right to freely sell their holdings. Gladstone's government also passed the Arrears of Rent (Ireland) Act 1882, which cancelled rent arrears for Irish tenants occupying land worth less than £30 per annum who were unable to pay.
