LONDON — Attorneys for WikiLeaks founder Julian Assange continued to hit at the credibility of the case against him during the second day of his extradition hearing Tuesday, calling two witnesses who condemned the handling of the sexual assault accusations against him by authorities in Sweden.

But the testimony of both witnesses also appeared to backfire in part on the 39-year-old Australian, particularly that of a former Swedish prosecutor who conceded that authorities in Sweden might have rightfully issued a warrant for Assange’s arrest. The witness also cast doubt on defense claims that Sweden would extradite him to the United States.

Assange, who is wanted for questioning in Sweden on allegations of sexual molestation, unlawful coercion and rape, sat in the courtroom wearing a dark suit and burgundy tie for what was set to be the final day of his extradition hearing.

But as testimony continued, Judge Howard Riddle signaled the trial would instead adjourn until Friday, when closing statements will be heard. Riddle might reserve immediate judgment and instead issue a written verdict in the days ahead. But experts predict a final resolution to the extradition process might not come for months, given the various routes for legal appeals.

The hearing will determine whether British authorities will honor a Swedish warrant for Assange, who is under partial house arrest in Britain as he fights extradition. The warrant hinges on allegations by two Swedish women with whom Assange had brief affairs in Stockholm in August. Both claim that specific encounters with Assange became nonconsensual, with one saying he engaged in unwanted, unprotected sex with her while she was asleep, an act considered criminal rape in Sweden.
