The ILC's first special rapporteur on state responsibility, F.V. García Amador of Cuba, appointed in 1955 noted, "It would be difficult to find a topic beset with greater confusion and uncertainty." García Amador attempted to return to the traditional focus on responsibility for injury to aliens but his work was essentially abandoned by the ILC when his membership ended in 1961. His successor, Roberto Ago of Italy, reconceptualised the ILC's work in terms of the distinction between primary and secondary rules, and also established the basic organisational structure of what would become the "Draft Articles". By focusing on general rules, stated at a high level of abstraction, Ago created a politically safe space within which the ILC could work and largely avoid the contentious debates of the day. From 1969 until his election to the ICJ in 1980, Ago completed work on part 1 of the draft articles, addressing the origin of state responsibility. Most of the thirty-five articles adopted during his tenure are reflected in the final draft.
