No, Pasteur proved that enormous multicelled creatures - maggots, IIRC - do not spontaneously form from meat left in a jar within a few weeks.
Abiogenesis is the theory that organic chemicals came together & formed autocatalytic or cross-catalytic relationships that kept replicating themselves, thus keeping their existence above the general "chemical noise". If so, some of the principles of evolution would apply here, though it's really still just chemistry. Eventually (maybe even several million years later) some such catalytic molecular colonies excreted bubble-like bags around themselves, thus segregating into individual metabolic entities. ("AKA cells.") These cells continued to reproduce themselves, and only at that point does biological evolution per se enter the picture, because only then do the self-replicating entities begin to fit the traditional definition of "living organisms".
This has nothing to do with Pasteur, nor with any "Law of Biogenesis". The Biogenesis Police keep pulling abiogenesis over, but he keeps getting it thrown out of court.
