Here’s what article 14 says:

Article 14

1. Everyone has the right to seek and to enjoy in other countries asylum from persecution.

2. This right may not be invoked in the case of prosecutions genuinely arising from non-political crimes or from acts contrary to the purposes and principles of the United Nations.

The principle behind this article only applies to genuine cases of political prosecution, where the person seeking refuge is doing so in good faith. Countries can and often do reject asylum cases where the person seeking asylum either lies on their application or commits serious crimes inside the country they’re seeking refuge in. I don’t see these individuals being deported as a violation of this article.
