As a point of clarification, the statute on which most of our comments and interventions are based today is the Environmental Assessment Act, which came into force in 1995. Prior to 1992, this would have been under the previous regime, which was the environmental assessment review process guidelines order, which was similar in some ways to, but markedly different from, the statutory regime we have in place now.
