If the two circles in this scenario are linked, then the responsibility to align between the two circles lies in the links. If not, then a good first step is to give feedback and give the circle a chance to respond. Your governance agreement might define a process of how that is best done, e.g. by email or by visiting a meeting of that circle. Mutual understanding and feedback typically go a long way.
Some governance agreements put in place an appeal process but this should always be very last resort because it is at odds with the basic values of distributed authority.
