Any time that a bill will amend existing law, the legislation will show the current law and then cross out the existing language and replace it with the proposed changes.
At this time, the legislature has asked optometry and ophthalmology to negotiate amongst themselves. With that agreement given by both parties, the bill has those lines stricken to clarify more than anything else the practice of optometry in CA.
Should the negotiations fail to create an agreement, it is likely that the legislature will remind both sides (mainly ophthalmology) that the legislative intent of the last bill, SB 929 (Polanco, Chapter. 676, Statutes of 2000) was created with the understanding that no redefinition bill would come up before the legislature for 10 years. In consideration, both sides gained equal shares of what they wanted. Optometry agreed to withhold any new efforts at redefinition for 10 years. It is now 10 years past and we find ophthalmology and optometry again negotiating hopefully in earnest to come to some common ground for a new bill.
I'm sure both sides are resolute but legislative intent is a funny thing. Despite what ever rash or deliberately inflammatory language that is used by any side, the legislature seems to be quite pragmatic on this subject and is grounded in achieving a settlement and has reminded that both sides agreed to the truce in the aftermath of AB 929. Neither is the legislature swayed by any kind of extremism or subterfuge by either side that will detract from a result. Organized optometry has met its promise by awaiting 10 years and awaiting ophthalmology to meet theirs.
If the legislative intent is not observed, I can foresee the legislature not avoiding the subject but crafting something else which might surprise both sides. If either side wants a better say in the final bill, I would recommend that negotiations be done in a more good faith manner than I think has transpired over the last year and a half.
By the way, ophthalmology has known full well what the shape of the SB1406 might take for some time before its introduction. This is part of the legislative intent that was hammered 10 years before.
