ST. PAUL, Minnesota (CNN) - Minnesota voters who say their absentee ballots were rejected for no good reason took the witness stand Tuesday in the second day of the trial requested by former Republican Sen. Norm Coleman, who once again was on hand for the proceedings.
Coleman is contesting Minnesota's Senate recount results, which put Democrat Al Franken ahead.
It was an abbreviated day of testimony - the three-judge panel spent all morning in a private meeting with each side's lawyers to iron out details for how the case would proceed. Still, Coleman attorneys called seven witnesses to testify, six of whom they say are voters whose ballots were rejected in error.
Their seventh and final witness of the day was Deputy Secretary of State Jim Gelbmann, played a key role during the recount process, particularly on the issue of rejected absentee ballots - the focal point of Team Coleman's arguments so far. They say approximately 4,500 ballots that weren't counted were valid, and should be back in play.
The six voters who took the stand range from a man who said, according to a letter from the state, that his ballot was rendered moot due to a mispelling in his name to yet another man whose ballot may have been rejected because his girlfriend signed his signature on his ballot application while he signed the actual ballot, meaning the two signatures did not match.
Gelbmann, who spent more time on the stand that any of the six voters who preceded him, said in his testimony that he trusted the decisions made by local election officials but admitted that human error was possible.
"They could have made mistakes," Gelbmann said, while making the point that in order to truly know what happened in each specific instance the local election workers should be consulted.
"Every one of these envelopes has a story behind it," he added.
Speaking to press after the day's hearings, neither campaign would say specifically what would be on tap for Wednesday, but Coleman attorney Ben Ginsberg alluded to the possibility of more voters and local elections officials.
