Tracing the development of international legal protection of freedom o
f association, Swepston highlights the pioneering role of ILO Conventi
on No. 87 and the consistency of the relevant provisions in a number o
f subsequent UN and regional instruments. Over the years the ILO's sup
ervisory bodies have refined the legal implications of that protection
by underlining links between freedom of association and the whole ran
ge of civil rights and liberties. The vitality of the ILO's supervisor
y process is evident in developments within subjects covered by Conven
tion No. 87, including establishment of organizations, their activitie
s, the right to strike, affiliation, and many more.
