well he just seems like a stand up , old school gangster who understands LCN politcs and is respected across the board. No one ever said a bad word about larry. Also he is the capo of the biggest crew in the family whch shows he has leadership skills.

At a few other times in the show when major decisions are being made people go to larry. Example when juinor and richie want to take out tony junior send riche to make sure they would have larry behind them. Shows he is a powerful player wthin the family.

A rulng panel is also a possibility. Larry suggested it when tony and junior was going at it in season 1. Larry, Sil and paulie possibly?
