Other points raised by Simpson's team included Galanter's failure to hire investigators or experts and never interviewing witnesses against Simpson because, "We already knew a lot about them."
A key criticism was Galanter's refusal to hire experts to analyze audio recordings from the hotel incident, telling a colleague they were "operating on a shoestring" while demanding more money from Simpson's business manager. He also refused to challenge admissibility of the tapes, insisting they would help Simpson.
Jurors said they convicted Simpson solely on the basis of the tapes because they found the witnesses not credible.
When the hearing ended, the judge said would issue a written ruling but did not set a date.
If Simpson succeeds in getting his conviction thrown out, prosecutors will have to either retry him or offer a plea bargain. It is also possible Simpson could be freed with credit for time served. If he loses, he will be sent back to prison and will probably appeal to a higher court.
He will be 70 before he is eligible for parole.
