There are organizations and individuals whose business is objecting to natural resource projects, particularly those of the extractive industries. Administrative appeals and legal challenges have the goal of delaying or stopping projects. Effectively refuting their claims saves proponents, consultants, and attorneys time and money. A common tactic used by project opponents is to claim that “we think|believe|feel…” the proposed project will have significant negative impacts. Supporting data or objective substantiation of this claim are not required for acceptance by the regulator or court. However, the project proponent is required to respond to the allegation using data and objective methods. While a level playing field would be great, there are effective ways to support rejection of the appeal or legal challenge.
