As a legally authorized AHJ, I do get to approve the connection (90.4 & 90.7 & the definition of AHJ in 100).
If I feel that a grounding or bonding connection choice is not sufficient to provide a low impedance to ground, then I can, and do, refuse to allow it (250.4(a)(3)(4) & (5) and the definition of bonded in 100).
I can and do sometimes reverse my decisions upon the submission of additional information or test results. My decisions can also be appealed to a higher authority (90.6 and local regulations).
I do not hold a grudge, the aim is a safer installation (90.1(A)), and I choose to err on the side of caution.
