Where a Commission is appointed under section 80 of the Urban Councils Act to govern a municipality in place of a normally elected Council, and the Act does not make specific provision for how such a Commission should conduct itself, the Commission may lawfully combine the functions of the full Council and the Executive Committee. Where all Commissioners constitute the Executive Committee, the two bodies are indistinguishable and it is not necessary for the Executive Committee to seek approval from the full Commission under another guise. A decision to dismiss an employee will not be set aside as grossly unreasonable where it is based on properly conducted disciplinary proceedings that made findings of incompetence, negligence and inefficiency, and where the only contrary recommendation was merely a plea for mercy that did not dispute the findings or challenge the legal basis for dismissal.
