Insider activism refers to situations where public officials use administrative discretion to advance personal or ideological preferences. Although the concept has received increasing attention in organizational and political science research, empirical evidence remains limited. This research note examines whether insider activism may influence regulatory practice in the Swedish forestry sector and how perceived enforcement uncertainty affects forest owners' behavior. A survey of forest owner representatives in southern Sweden indicates low trust in regulatory objectivity and weak perceptions of legal security. Many respondents report experiences of officials acting beyond their formal mandate. The findings suggest that perceived activism-driven uncertainty encourages defensive strategies among forest owners, including early harvesting and reduced willingness to report environmental values.
