Brown's veto of Assembly Bill 375 marks the second straight year that high-profile legislation aimed at facilitating the teacher dismissal process failed in California. Last year, a measure by Sen. Alex Padilla, D-Los Angeles died in committee.
Proponents of the bill have argued that districts face a prolonged, costly fight when they move to fire teachers. While this year's measure won the crucial support of the California Teachers Association, Brown repudiated it, saying in his veto message that the bill could "make the process too rigid and could create new problems."
The bill would have limited the amount of time that a case can take after a district formally files dismissal charges and would have lifted a ban on issuing dismissal notices during the summer months. In his veto message, Brown praised the bill for curtailing "opportunities for delay."
But the governor cited concerns about language limiting the number of depositions both sides can invoke in firing disputes - five total - and rules governing whether districts can use newly surfaced evidence to alter charges.
"I share the authors' desire to streamline the teacher discipline process," Brown wrote, "but this bill is an imperfect solution."
