AB1381 Council of Mayors:

In exercising any of the duties described in this chapter, the council of mayors shall act by a majority of the weighted vote of the total membership of the council. The weighted vote of each member of the council of mayors is equal to the proportion of the population of the LAUSD that are residents of the city of the individual member, or unincorporated area of the county for any member of the county board of supervisors, to the total population of residents of the LAUSD.

In other words, Mayor Villaraigosa is in charge!
