# 4 法律、內容限制命令，和實務做法必須通過必要性和比例原則的檢驗

在一個民主社會中，法律、內容限制命令，和實務做法必須具備必要性並合乎比例：

1. 所有內容限制必須局限於特定之爭議內容。
2. 在對內容進行限制時，必須採用限制性最低的技術手段。
3. 如果內容是因為在特定地理區域屬於違法而被限制，而中間人針提供因地域而異的服務，那麼內容限制應局限於該地理範圍內。
4. 如果內容是因為在一定期間內屬於非法而被限制，那麼限制不能持續超過該期間，並應該定期檢視限制命令以確保其仍然有效。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://nninlaw.gitbook.io/manila-principles/4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
