The judge issued a default judgement against Jones for persistent refusal to meet discovery obligations. The jury trial was about damages, not liability (“guilt” is not strictly at issue, since it is a civil and not a criminal case.)
Default judgement is a sanction available for that kind of persistent misconduct in civil cases. (And Jones has two more of them in Sandy Hook cases for the same reason, one in the same Texas court, another in Connecticut. The default judgements in both Texas cases refer to the noncompliance in all three cases in their factual background.)
What happened recently and in the news was just the jury determining the size of the punishment.
Nitpick: default judgement. Summary judgement is a different thing.
