No he can't; no civilian court has jurisdiction to collaterally attack a decision of a court martial.
If Kalid Sheik Mohammed can get a trial in civilian court ... why not Mr. Lakin?Mohammed is scheduled to have a criminal trial in a civilian court. If he is convicted in that case, he will not be able to bring a civil suit "for fraud and damages."
But a Citizen can sue a president for Fraud. We saw Paula Jones sue a president for sexual harrasment.
Fraud is crime. Lakin will have damages.
