RELATED INSIGHTS

Thailand’s Supreme Administrative Court has issued a decisive ruling annulling the Ministry of Labor’s notification that had granted an exemption for foreign pilots to fly domestic routes under wet‑lease arrangements. A wet lease is a leasing arrangement in which the aircraft is provided together with its foreign flight crew, including pilots, and related operational support, rather than the airline supplying its own pilots. The judgment, delivered on November 17, 2025, and published in the Government Gazette on January 30, 2026, follows a legal challenge brought by the Thai Pilots Association, which argued that the exemption unlawfully enabled foreign workers to assume a role traditionally reserved for Thai nationals. The notification in question, dated December 13, 2024, authorized foreign pilots who came as part of wet‑leased aircraft to fly domestic routes. The Thai Pilots Association disputed the legality of this rationale, asserting that the exemption was triggered by a private airline’s request rather than by any statutory necessity. The Ministry of Labor justified this measure by relying on aircraft‑specific approvals issued by the Ministry of Transport and by enabling the Department of Employment to issue corresponding work permits. Arguments Presented in the Case The Thai Pilots Association argued that the exemption undermined the interests of domestic pilots and conflicted with the policy intent of Thailand’s foreign‑worker regulatory framework. The lawsuit emphasized that the notification arose directly from a private airline company’s request to operate two A320 aircraft under a wet lease and that the measure had the practical effect of displacing Thai pilots who remained unemployed. Meanwhile, the Ministry of Labor defended the exemption as a temporary and necessary response to industry shortages and part of national efforts to support tourism and restore aviation capacity. Legal Framework Thai law establishes a general prohibition against foreign nationals piloting domestic aircraft. Section

Thailand has expanded the circumstances under which state agencies may bypass competitive bidding procedures to address urgent security challenges. On November 28, 2025, Thailand’s Ministry of Finance published the Ministerial Regulation Determining Cases of Procurement by Specific Method (No. 6) B.E. 2568 in the Royal Gazette, introducing a new pathway for procuring supplies and services needed to address cyber and military threats that may affect the stability of government agencies or the nation. For technology vendors, cybersecurity firms, and defense contractors, this regulatory change creates immediate opportunities to engage directly with government buyers facing urgent security challenges. New Fast-Track Category for Security Threats The regulation amends Thailand’s Public Procurement and Supplies Management Act B.E. 2560 (2017) to add a new category of procurement that qualifies for the “specific method”—a noncompetitive, direct selection process. Previously, agencies could use this expedited method only in limited circumstances, such as emergencies, cases with proprietary technology requirements, or national security operations. The new provision explicitly covers procurement of supplies related to preventing or resolving cyber or military threats that could impact the stability of a state agency or the country. This addition recognizes the urgent nature of modern security challenges, where competitive bidding timelines may leave agencies vulnerable during critical threat windows. State agencies dealing with active cyberattacks, preparing defensive measures against anticipated threats, or responding to military security concerns can now move directly to negotiate with qualified vendors rather than conducting lengthy public tender processes. Vendor Considerations Vendors offering cybersecurity solutions now have a regulatory avenue to work directly with government clients when stability concerns are present. These solutions include threat detection systems, anti-ransomware tools, incident response services, firewalls, and security consulting. Similarly, defense contractors providing military equipment or specialized security supplies can pursue direct engagement channels where traditional procurement methods would create
