Great bodily injury does not require loss of limb or permanent disability as a result in CA law either. I was a juror in The People Of California versus Robert Mills in 2000 and we (the jury) found Great Bodily Injury as an aggravating factor in the case of three separate knife wounds where Mills had cut a tendon in his wife's hand that needed reconstruction and a (relatively) shallow wound in the vicinity of her kidney that cut skin and striated tissue only and a small scar by her eye.
Not making light of her injuries, just pointing out that once criminal intent and guilt was established on separate counts Great Bodily Injury does not have a high burden. BTW Judge Kroyer sentenced Mills to 22 years 4 months. I never lost sleep over it, I never told the POS to attempt to murder his wife.
