Thanks to Ian Lind for a straightforward, clear explanation.  

Kale Gumapac was a homeowner whose property was foreclosed after he failed to pay his mortgage, which he did because of reliance on Sai's theory about illegal occupation of Hawaii by U.S. and lack of jurisdiction by federal or (puppet regime) state courts.  Sai and Gumapac have had numerous joint appearances on TV podcasts.  Sai has been causing a lot of pain to a lot of people for more than 20 years as he pushes his absurd historical and legal theories, and Kaiama has been engaging in abuse of legal process in support of Sai.  It's long past time for the Supreme Court to rein them in.  For in-depth explanation of what's going on, see webpages
