A federal hearing Monday may show who’s really the Zulu king, or at least who’s legally entitled to use the Mardi Gras krewe’s name on Facebook.

Zulu Social Aid & Pleasure Club Inc. filed a trademark infringement suit against former associate member Jeffrey P. Guice over his “Zulu Mardi Gras” Facebook page. The lawsuit also says Guice used club trademarks without permission in attempting to sell spots on a Zulu float, invitations to the Zulu Mardi Gras ball and a Zulu coconut.

Zulu has asked the court to prevent Guice from continuing to use the Zulu trademarks. The club says Guice’s actions have caused “irreparable injury” and asks the court for damages and attorney’s fees.

Zulu has asked for a temporary restraining order against Guice. A hearing is set for 3 p.m. Monday at U.S. District Court in New Orleans on the issue.
