The study finds that the strength of a human-rights treaty’s control mechanism moderates the effect of the political regime on how states commit to HR treaties. Empirical test of the “moderation effect hypothesis” showed that the overall speed of the commitment process of communist Czechoslovakia and newer democratic regimes (CR and SR) was quite similar. However, while communist Czechoslovakia preferred commitments to treaties with weak control mechanisms, the transitioning CSFR and its democratic successors were more prone to ratify treaties with a strong control mechanism.
