What is the Sharia ruling on restricting marriage and not judging by outward appearances when marrying women in Libya, despite the hadiths that command judging people by their apparent deeds?

"The regulations and laws enacted by states to restrict permissible things must be followed, as long as they achieve a public interest or ward off a real harm, because the ruler's actions are contingent upon public welfare. This is supported if, in its application, the reality and the balance of benefit and harm are considered. The estimation of this is referred to the people of knowledge in Libya."
