Texas Attorney General Ken Paxton is suing the developers of a planned Islamic community in East Plano, framing it as a stand against Sharia law — bad news for the project, good news for conservatives who want to block it.

• The East Plano Islamic Center (EPIC City) got local approval, but Paxton's office is suing over alleged violations of state securities laws and board governance rules.
• Paxton says Sharia law cannot coexist with the US Constitution and will not be tolerated in Texas, even if other states allow it.
• He points to Europe and Michigan as warnings, saying Texans do not want separate legal systems running in different communities.
• A possible federal angle: fair housing law, since the project is described as an all-Muslim community, which could count as religious exclusion.
• Conservatives argue if the project succeeds in Texas, similar developments will spread to other states.

Outlook: The lawsuits will drag on, and the fight will likely become a national test case for how far religious community projects can go under US law.
