Queensland Deputy Law Practice Exam 2026 - Free Deputy Law Practice Questions and Study Guide

The correct answer is the industrial magistrate, who possesses the authority to suspend or cancel a certificate of competency under the relevant mining legislation. This is typically part of a regulatory framework designed to ensure safety and compliance in mining operations. The industrial magistrate's role is critical in overseeing adherence to legal standards and ensuring that professionals operating in the mining sector meet requisite competencies.

In many jurisdictions, the chief inspector may have the power to assess or enforce compliance but does not possess the direct authority to suspend or cancel certificates. The site senior executive is responsible for site operations and safety management rather than the formal licensing or certification process. Meanwhile, the mine owner's responsibilities are generally centered around managing the mine and its operations rather than making decisions about the certification status of individual workers. Thus, the industrial magistrate is the most appropriate authority for these actions concerning competency certificates.
