Is there any issue with stunned halal meat?

It is closer to the Sunnah to avoid stunning and there's no doubt or difference of opinion about this. However, if an animal is slaughtered and it's stunned beforehand, does that mean that the meat is haram? And the answer is no, as long as the animal does not die when it is stunned. Nowadays a number of different halal monitoring authorities and councils have mentioned that the voltage used is so low that it would not be possible for the animal to die when it is stunned. So if this is the case with the particular authority that is verifying the meat or the restaurant have mentioned that this is the case, that it's been certified as halal from a particular authority, then there's no issue with it because the animal has not died or has not been killed before it has been made halal.
