Accused criminals don't get to set the rules. There are many jurisdictions where criminal trials in absentia are not possible, legally. That's mostly to the benefit of the accused.
How? if they can get a conviction they should get the conviction. For eg, Vijay Mallya from india was convicted of a crime and india is now seeking his extradition. how does it make sense that you keep the case open?
Mostly it's due to the accused's right to confront the accusations and be heard. There is also a lot of ugly history of using trial in absentia to, for example, get rid of political enemies: quickly convene a trial and convict them while they are abroad, avoiding a long trial allowing them to make their case and forcing them into exile.
He is charged with different crimes and therefore there is a warrant out, and a request for extradition: "When he failed to appear, the Supreme Court said the contempt case would only proceed further after he is produced before the court".
There are also multiple court verdicts in favour of banks and business partners, but those are all civil law, not criminal.
