Background and aim: Today, law evasion is considered a social and managerial challenge that hinders societal development. Its primary consequences include diminishing public trust, endangering security and stability, and undermining democratic values and ethics. This research aimed to design a model of the factors influencing law evasion in government organizations of Gilan Province.Method: This applied research is descriptive-survey in nature and follows a developmental mixed-methods approach. The qualitative sample consisted of 18 experts, university professors, managers from regulatory bodies, and judges from the Administrative Justice Court, selected through purposive non-probability sampling. The quantitative population comprised all employees of government organizations in Gilan Province, from which 382 participants were selected using Cochran’s formula and stratified random sampling. Data collection involved the Delphi panel for the qualitative phase and a researcher-made questionnaire for the quantitative phase. Data were analyzed using the Delphi technique (qualitative) and structural equation modeling (quantitative) via SPSS 26 and SmartPLS 3 software.Results: The findings identified six main factors—economic, political, cultural, structural, supervisory, and individual—as well as 15 variables influencing law evasion in government organizations. Based on this, a model was developed to understand the contributing factors.Conclusion: The qualitative results ranked the factors by influence on law evasion: economic, political, cultural, structural, supervisory, and individual. The quantitative results confirmed the model’s good fit. Additionally, the most influential pathways identified were from economic factors to structural factors, and from structural factors to supervisory ones.
