網路霸凌問題在台灣存在許久，是否訂定專法至今未有定案，本研究參照奉言論自由為最不容侵犯的美國與加拿大訂立專法經驗，探討網路霸凌專法與憲法保障言論自由的辯證，論述台灣如何以及為何要設立網路霸凌專法。本研究認為基於法律的保護他人原則、倫理學的目的論、道義論和折衷論觀點，設立網路霸凌專法與憲法保障言論自由不相悖。此外，設立專法可以採取緊急處份或簡易庭方式，先行刪除網路霸凌內容，保護受害者，再進行後續的審判。法律應該是與社會現況結合，跟上傳播科技的快速發展，而不是固守當前的做法，讓網路霸凌繼續發生。

The problem caused by cyber-bulling has existed in Taiwan for a long time, no consensus has been reached regarding the necessity of enacting an anti-cyber-bulling act to solve the problem. This study reviews the American and Canadian laws which deal with the social disturbance caused by cyber-bulling. The two countries’ cases involve the dialectic between freedom of speech and the anti-cyber-bulling acts. The American and Canadian’s experiences of dealing with cyber-bulling also pinpoint the necessity of making laws to decrease the cases of cyber-bulling. Thus, this researcher believes that making a law to deal with cyber-bulling does not limit the freedom of speech. Besides, from the perspectives of deontology or teleology, it is an ethical decision to make a law of anti-cyber-bulling. After the law is enacted, the cyber-bulling speeches can be judged by a summary court and be restricted to protect the victims. Overall, the legislative works should recognize the potential harms of the rapid spreading bulling speeches in the Internet websites and make a special law to deal with this problem.
