海域執法係國家安全的基石，社會及經濟穩定的助力，科技的進步及人權高漲已是國際社會之趨勢。人民對法律執行的要求，已由被動轉而期待法律須符合時代潮流；演變迄今，對法律內容質疑的觀念，執法品質與標準，更而有主動審視能力。依大法官釋字第535 號解釋文要旨，人民對個人擁有基本權利之重視程度，尤其權利限制或禁止，執法人員更應謹慎嚴竣面對及維繋人民擁有之權益。行政院海岸巡防署為我國海域執法專責機構，其執法範圍包括內水、領海、鄰接區、經濟海域、大陸礁層至公海等，兼具國內與國際執法能量的巡防機關。所執行的法律，不僅要迎合國家情勢與社會人民期待，更需要符合國際海洋法所賦予沿海國管轄權利。 接近權、緊追權、登臨檢查權乃海域執法實施態樣中，與人民權利義務關係密切，且會侵害人民各種基本權利，由大法官釋字第535號解釋文可得知其對人民個人基本權利之重視程度，因此，為了維護人民權利，海域執法人員更應審慎面對。如有發生違法或不當情形時，並應給予人民有救濟之機會。 海域執法方式亦可分為對人、對物之執法及對船接近權、緊追權、登臨權方式，並討論海域執法方式及海域執法程序，且因海上執法程序包括攔停、登臨及行政檢查等程序，次再探討海域執法與刑事搜索、行政檢查之區別，最後再分析海巡機關執行行政檢查之相關問題點。巡防機關人員職權之行使困難度甚於陸上警察。基此，訂定專屬海岸巡防機關於執法時所依據之職權行使法律，務必能與法定任務相結合，以保障執法人員自身安全與民眾自由權利。 / Maritime law enforcement is the fundamental issue for the national security as well a great component for the social and economic stability.
