Senator ROBERTS (Queensland) (16:30): I move: That the Senate notes that: (a) valid scientific data proving cause-and-effect is vital as the only credible justification for policies claimed to be based on science; and (b) the ultimate arbiter of science is empirical scientific evidence, being: (i) objectively verified hard data as physical measurements and/or physical observations, and (ii) presented in a logical framework proving cause and effect.
