As part of freedom of speech, lawyers’ extra-court speech should be a natural right that accompanies the birth of this profession and is inalienable. Restrictions on it should only be limited to not violating the same freedom enjoyed by others. An environment that tolerates lawyers’ extra-court speech helps shape civil society and promote press freedom. The legal basis for the legitimacy of lawyers’ extra-court speech is mainly the value presupposition of the theory of original evil, the principle of “rule of law” and the cost-benefit analysis of law and economics. The regulation of lawyers’ extra-court speech should follow the principle of minimum regulation. As long as the speech does not exceed the necessary obligation boundaries, ethical boundaries and group boundaries, no more restrictions should be imposed on it.
