Key among Simpson's 19 claims of ineffective assistance of counsel and conflict of interest being considered by District Court Judge Linda Marie Bell is the allegation that Galanter should have provided witness testimony supporting Simpson's contention that he didn't know he was breaking the law.
Simpson says the two even talked about it over dinner the night before the ill-fated confrontation in September 2007, and that Galanter told him that if Simpson recovered the suit he wore the day he was acquitted in Los Angeles, Galanter would like to have it.
Bell has made no indication whether she plans an immediate ruling or will issue a written decision later.
The most damaging testimony about Galanter's performance came from three other lawyers involved in the case: Gabriel Grasso and Malcolm LaVergne, who represented Simpson, and Brent Bryson, who represented a Simpson co-defendant who also was convicted.
Each said Galanter seemed more interested in what he was paid and protecting himself from having to testify than in fully representing his client.
LaVergne, who argued with Galanter when both worked on Simpson's appeal to the Nevada Supreme Court, testified Thursday that he believed Galanter's involvement shaped his trial strategy.
But stepping away from the case would have cost Galanter hundreds of thousands of dollars in fees.
"Do you think Mr. Galanter made decisions based on a conflict of interest?" Simpson lawyer Patricia Palm asked.
"From what I know now, absolutely," LaVergne said. "There's no doubt about it."
