What is really at stake here is the blatant confusion between a temporal correlation and a legal causality.
The decline in investments did not 'trigger' the quotas; at most, it served as an opportunistic pretext or a justification for a pre-existing and carefully considered regulatory intervention.
It is absurd to suggest that a simple drop in investments could, on its own, 'trigger' a government policy as complex as the implementation of local content quotas.
Regulatory measures require thorough impact studies and consultations, as Australian parliamentary debates show, long before an 18% decline becomes a sudden catalyst.
