Summary
The official reading of the Treaty is that of its text and of the bodies that apply it. Its first article reserves Antarctica for peaceful purposes while allowing military personnel and equipment when they serve science or another peaceful aim; this is why uniforms and military aircraft appear on the continent without breaching anything. Article III makes scientific observations and results freely available. Article X makes each Party responsible for ensuring that nobody engages in activity contrary to the Treaty, which is the origin of national permit and notification schemes. The Environmental Protocol adds that inspection reports and notifications are circulated to all Parties and made publicly available. Above all, Article IX provides that measures adopted at the Consultative Meetings become effective only if all the Parties entitled to take part approve them. A worldwide ban on visiting the continent would therefore have to be adopted unanimously and published, not hidden. National authorities do ask for notification: the US State Department, for example, requests three months' notice before a private expedition. According to the official reading, these duties apply the Treaty's advance-notice rule; they do not prohibit anyone from going.

Under Article IX, measures recommended at the Consultative Meetings become effective only when approved by all the Contracting Parties entitled to take part, so a continent-wide measure would need the approval of every one of them.

The measures referred to in paragraph 1 of this Article shall become effective when approved by all the Contracting Parties whose representatives were entitled to participate in the meetings held to consider those measures.

Article I states that the ban on military measures does not prevent the use of military personnel or equipment for scientific research or any other peaceful purpose, which explains why soldiers and military aircraft are seen on the continent.
