Observers got their first taste of what the 2013 legislative session might bring when lawmakers started pre-filing bills on Monday. More than 250 bills were submitted on the first day of pre-filing, with the majority focusing on education, civil and criminal law, and health and human services related matters. Only one bill related to immigration was filed, surprising session watchers, who’ve in the past seen legislators tripping over themselves to file multiple bills on the matter. Sen. Judith Zaffirini, D-Laredo, won the distinction of filing the most bills, with a total of 30.
