Disciplinary action issues against government officials under the 2018 Constitutional Act on Prevention and Suppression of Corruption

Natthamon Dasalee — 2026-08-18

This academic article aims to study the background, concepts, and theories regarding disciplinary actions against government officials, as determined by the National Anti-Corruption Commission (NACC) in its decision to indict government officials under the 2018 Organic Act on the Prevention and Suppression of Corruption. Numerous legal issues have been identified, and these issues will be analyzed and researched for the improvement of the processes. Successful international concepts and theories in disciplinary actions will be adapted for Thailand, ensuring the compliance with the rule of law.

The framework for this analysis includes legal issues under the 2018 Organic Act on the Prevention and Suppression of Corruption regarding disciplinary action against government officials, as determined by the NACC in its decision to indict government officials. Various concepts and theories are used, and a comparison of the disciplinary action laws against government officials in France, the Federal Republic of Germany, the United States, and Japan is performed to develop and to amend these laws. This will lead to the development of appropriate and internationally recognized disciplinary action against government officials.

The analysis found that several legal issues need to be developed, improved, and amended: 1. Problems related to the powers and duties of the NACC in investigating and making

disciplinary findings. The duties and powers regarding disciplinary findings should be clearly stipulated in the provisions concerning the powers and duties of the NACC. 2. Problems of legal equality in disciplinary proceedings and disciplinary punishment. Amendments should be made to ensure legal equality. 3. Problems of restricting the rights of the Civil Service Protection System Commission (CSPCC) in considering and deciding the appeals. Amendments should be made to grant full rights to the CSPCC in its consideration to ensure fairness for those who are punished. 4. Problems related to the request for a review of the NACC's disciplinary findings. The timeframe for the request for a review of the NACC's findings should be appropriately amended to further facilitate justice to the accused person.

The objectives of this research were: 1) to study the level of solid waste management (SWM) behaviors among residents, 2) to examine perceptions of Tha Khlong residents regarding SWM information disseminated through municipal communication channels and promotional projects, 3) to examine the level of public participation in SWM, 4) to compare SWM behaviors based on personal factors, 5) to examine the relationship between perception of municipal communication channels and promotional projects and SWM behaviors, and 6) to examine the relationship between public participation and SWM behaviors. The sample consisted of 398 residents living in the Tha Khlong Municipality area, determined by using the Taro Yamane formula for sample size calculation. Data were collected using questionnaires and analyzed by statistical methods, including frequency, percentage, mean, standard deviation, independent samples t-test, one-way ANOVA, chi-square test, and Pearson’s correlation coefficient (r), with the significance level set of .05.

The research findings indicated that the SWM behavior of the residents in Tha Khlong Municipality was at a moderate level. The perception of information regarding waste management from the municipality's public relations channels and the perception of the municipality's SWM promotion projects were also at a moderate level. Overall public participation was found to be at a moderate level. Hypothesis testing revealed that some personal factors, namely; age, occupation, number of family members and duration of habitance, had a significant difference in relation to waste management behavior, while gender and educational level showed no significant difference. It was found that the perception of information from the municipality's public relations channels and the perception of the municipality's waste management promotion projects were significantly correlated with the residents' SWM behavior. Furthermore, participation in decision-making, implementation, benefits taking and evaluation were significantly correlated with the residents' waste management behavior at the level of .05.

Legal Issues Concerning Consent for the Collection, Use, and Disclosure of Personal Data under the Non-Life Insurance Act B.E. 2535 (1992)

Chon Prasuwan — 2026-08-18

The study entitled “Legal Issues Concerning Consent for the Collection, Use, and Disclosure of Personal Data in Non-Life Insurance Business” aims to analyze the inconsistencies between the Non-Life Insurance Act B.E. 2535 (1992) and the Personal Data Protection Act B.E. 2562 (2019). The study focuses on key issues, including the principle of consent for personal data processing, the disclosure of policyholders’ data to the Office of Insurance Commission, collection of excessive data beyond necessity and determination of the data retention periods. This research employs a qualitative methodology using documentary research. Relevant legal provisions, judicial decisions, academic literature and related legal documents are examined and comparatively analyzed to assess the consistency between the two Acts. The findings reveal that the Non-Life Insurance Act B.E. 2535 does not explicitly provide comprehensive provisions on personal data protection. Consequently, the protection of policyholders’ rights primarily relies on the enforcement of the Personal Data Protection Act B.E. 2562, which may lead to ambiguity in interpretation and practice, particularly regarding the legal basis for disclosure of data to state authorities, excessive data collection and fixed retention periods that may contrary to the principles of purpose limitation and proportionality. The study proposes amendments to the Non-Life Insurance Act B.E. 2535 to integrate consent and personal data protection principles in alignment with the Personal Data Protection Act B.E. 2562 in order to enhance legal clarity and promote a balance between regulatory oversight and the protection of policyholders’ privacy rights.

Toungtong Lapcharoensap — 2026-08-18

The objective of this study is to examine the problems and obstacles regarding brand engagement toward electric vehicles (EVs), and to investigate the effects of EV brand engagement on purchasing decisions. The sample group consists of 400 individuals who planned to purchase, currently used or had previously used electric vehicles in Bangkok and its vicinity, selected through simple random sampling. A questionnaire was employed as the data collection tool. The research findings revealed that the majority of the respondents were female and currently owned a personal vehicle. The hypothesis testing results indicated that all five engagement factors, namely; communication, product attributes, after-sales service, price and expenses and electric vehicle (EV) engagement significantly influenced EV purchasing decisions, with price and expenses exerting the greatest influence. Furthermore, the analysis of direct and indirect effects of EV brand engagement on purchasing decisions revealed that the variables predicting EV purchasing decisions had a significant direct effect. Regarding indirect effects, product attributes and price and expenses were statistically significant at the 0.001, communication was significant at the 0.01 and after-sales service was significant at the 0.05. Recommendations for future research include conducting in-depth analysis of individual electric vehicle (EV) brands to identify flaws and market gaps, enabling the development of products that better meet consumer needs. This should be accompanied by an examination of government policies to stimulate widespread adoption, such as tax incentives. Furthermore, research should explore public and private partnership (PPP) models for infrastructure development, including battery charging stations and dedicated parking spaces. Yet, study should be made focusing on enhancing vehicle efficiency for real life application.

The story portrays a love triangle among three characters: a young scholar, the daughter of a high-ranking minister, and a carp demon. 2) The performance format integrates Thai and Chinese cultural elements in performing arts, divided into three scenes: Scene 1 Love at First Sight, Scene 2 The Stratagem, and Scene 3 Fulfillment. The components of the performance include: (1) a theatrical script integrating dramatic performance with dance; (2) musical accompaniment combining Chinese instruments with synthesized sounds of Thai music; (3) a cast of nine performers (six females and three males) with acting and dancing skills; (4) movement styles incorporating Chinese dance, naturalistic gestures, and Thai classical dance; (5) costumes

Structural Dynamics and Gender Asymmetry in the Thai Labour Market: Evidence from a Shift-Share Decomposition

Kwan Phetsawang — 2026-08-18

This study examines structural change in Thailand’s labour market in the context of demographic transition and changes in the structure of employment. It draws on repeated cross-sectional data from Thailand’s Labour Force Survey, covering 68 quarters from the first quarter of 2007 to the fourth quarter of 2023. The analytical sample comprises employed wage earners aged 18–65 within the scope of the study. Occupations are classified into three task categories: abstract, routine, and manual. A shift-share decomposition is applied to separate changes in employment shares into three components: changes in workforce composition, within-group changes in employment propensities, and the interaction between the two components. The results indicate that, for several worker groups, particularly those with intermediate levels of education, changes in the employment structure are more closely associated with within-group shifts in employment propensities than changes in workforce composition alone. Gender and education specific estimates reveal a marked pattern of gender asymmetry. Among workers with primary to upper secondary or vocational education, employment propensity effects are negative for women across all three task categories This reflects limited scope for adjustment through reallocation across task categories. For men with the same levels of education, the effects are negative in abstract and routine tasks but positive in manual tasks, indicating that manual task employment may provide a partial adjustment margin for male workers. These findings suggest that structural change in employment is not gender-neutral. Labour-market policies should not therefore merely rely on broad-based supply-side upskilling. Greater emphasis should be placed on expanding access to quality jobs, supporting occupational transitions tailored to the circumstances of different worker groups, and strengthening social protection measures that address gender-specific constraints on labour market adjustment.
