No umpire has the authority to overturn another umpires call, nor should they ever seek to influence or change another umpires call without that umpire asking for assistance. Unless the calling umpire asked the plate umpire for assistance, the plate umpire needs to keep quiet. Even if the calling umpire does ask for additional information, the call is still theirs to keep or change.
