What's Kim Dotcom's status right now?
As of yesterday, he was considered liable for extradition. That means the court found there was enough evidence to justify a trial in New Zealand on the charges he faces in the United States -- criminal copyright violation, money-laundering and racketeering. That doesn't mean Dotcom is guilty, because the prosecution evidence has yet to be properly tested. This is not unusual as it matches what happens in New Zealand criminal trials. The extradition hearing equates to a "committal hearing" in the New Zealand criminal process, which means the police have to show there is enough evidence to bring someone to trial. In Dotcom's case, as in most committal hearings, the defence does not have much of a chance to argue evidence or make it's own case. That's what a trial is for.
What happens next?
Lots of appeals. The first appeal has already been filed within the 15-day limit allowed for in law. The basis of the appeal has to be on matters of law. The few strands of evidence allowed in the extradition hearing can't be relitigated, and no new evidence can be introduced. It is up to Dotcom's lawyers to argue at the High Court that the judge in the extradition hearing applied the law incorrectly. If the High Court doesn't agree with Dotcom's arguments -- or even if it does -- the case is likely to be appealed to the Court of Appeal and then the Supreme Court. It could take years.
What happens once the court process is finished?
