  • September 12, 2012 webinar regarding Governor Brown's pension reform package, AB 340, which made significant and far-reaching changes to public sector pensions in California. PORAC President Ron Cottingham joined Mastagni Law labor consultant Michael Jarvis and attorneys David E. Mastagni and Jeffrey R. A. Edwards to discuss the details of the new law, its impacts on CalPERS and 1937 Act jurisdictions, and how it affects current and new employees., The Public Employee Pension Reform Act What AB 340 Means For Public Safety, California Public Safety Employees, 2012
  • On December 16th, David E. Mastagni testified in support of public safety labor rights before the California Assembly Select Committee on Police Reform, Next Steps: Understanding Peace Officer Bill of Rights.  In defending the Public Safety Officers' Procedural Bill of Rights ("POBR"), David explained that the core of the POBR simply codifies basic labor rights to representation during a disciplinary investigation (i.e. Weingarten rights) and Constitutional Due Process rights to appeal a deprivation of officers' property interest in their continued employment.  , David E. Mastagni Testifies Before the Assembly Select Committee on Police Reform: Understanding Peace Officer Bill of Rights, Law Enforcement, 2021
  • On Tuesday, April 19, David E. Mastagni testified before the California Assembly against AB 2557, created by California State Representative, Mia Bonta. This appointed bill would make all law enforcement personal records public in any agency where a civilian oversight board has access to citizen complaint investigations, regardless of the nature of the allegations or whether they were sustained. The bill claims it would make police officers more accountable, however, the bill is not taking into account the risk of defamation, ridicule and harassment for innocent police officers due to the timing of released information before the officer is cleared. , David E. Mastagni Testifies Against AB 2557, Stating it Would Tarnish Innocent Police Officers, Privacy Rights, Union Rights, Law Enforcement, 2022
  • On April 26, David E. Mastagni testified in front of the Senate Public Safety Committee in opposition of S.B. 1088.  The Bill is modeled after recommendations to weaken peace officer due process rights issued by Ronald Yank and Barry Winograd, David's Labor Law professor at U.C. Berkeley School of Law.  In essence, SB 1088 would create a balancing testing which would deny officers a remedy for POBR violations if the seriousness of the allegations outweighs the significance of the POBR violation.  David pointed out that most POBR remedies are simply to exclude improperly obtained evidence or provide officers access to improperly withheld materials.  Ironically, the Bill would incentivize IA investigators to cut corners and violate procedural rights by eliminating agency accountability. , David E. Mastagni Testifies Against Bill to Limit POBR Remedies (SB 1088, Bradford), Union Rights, Law Enforcement, 2022
  • On June 28, 2022, David E. Mastagni testified on behalf of PORAC and CAHP against S.B. 505 (Skinner) which if enacted would erect new barrios for the exercise of Californians' Second Amendment rights.  The bill would make a person who owns a firearm strictly civilly liable for each incidence of property damage, bodily injury, or death resulting from the use of their firearm unless the owner of the firearm has reported their firearm to local law enforcement as lost or stolen prior to the damage, injury, or death. Additionally, S.B. 505 would require a person who owns a firearm to obtain and continuously maintain a homeowner's, renter's, auto, or gun liability insurance policy specifically covering losses or damages resulting from any negligent or accidental use of that firearm, including but not limited to, death, injury, or property damage. David testified that his law enforcement clients understand first-hand the scourge of gun violence.  Unfortunately, S.B. 505 will have little impact on individuals who commit crimes with guns, but will impose significant burdens on the Constitutional rights of law-abiding citizens. SB 505 cannot withstand the standard set forth in New York State Rifle & Pistol Ass'n, Inc. v. Bruen., David E. Mastagni Testifies Against S.B. 505 (Strict Liability & Insurance for Firearms) on Behalf of PORAC & CAHP, Constitutional Rights, 2022
  • In Anthony Sanders, et al. v. County of Ventura, current and former members of the Ventura County Deputy Sheriffs’ Association (“DSA”) and the Ventura County Professional Firefighters’ Association (“PFA”) filed an FLSA lawsuit challenging the County's unlawful pay practice of imposing an involuntary deduction from the earnings of employees who waive health insurance in order to defray the benefit costs of other employees.  The suit alleges the fee constitutes an illegal kickback of wages.  The County unilaterally imposed this "Opt-out Fee", which subsumes most of the Flexible Benefit Allowance (“Allowance”) paid to the Plaintiffs as income. On August 22, 2023, David E. Mastagni argued this case before the Ninth Circuit Court of Appeals. This appeal seeks reversal of the district court’s error in granting the County's cross-motion for summary judgment/adjudication based entirely upon its finding that the involved Flexible Benefits Plans were “bona fide” and the County’s cash-in-lieu payments were “incidental.”  The bona fide dispute is not dispositive of the claims raised in Plaintiffs/Appellants’ lawsuit.   The County admitted that the opt-out fee is first paid to Plaintiff as gross income within the meaning of I.R.C. § 61 and reflected in Plaintiffs’ paystubs as earnings. David argued that because the full Allowance is paid directly to Plaintiffs prior to the deduction of an “Opt-out Fee”, the fee cannot be excluded from the regular rate of pay. In short, plaintiffs contend direct payments to employees who waive health insurance, the opt out fee cannot be excluded from the employee’s “regular rate of pay” pursuant to 29 U.S.C. § 207(e)(4). Flores v. City of San Gabriel, 824 F.3d 890, 901-02 (9th Cir. 2016), cert. denied, 137 S. Ct. 2117 (2017).  However, this action is primarily a dispute over whether the fee constitutes an unlawful deduction for which Plaintiffs are entitled to restitution.  Because the FLSA involves overtime claims, the suit seeks restitution by alleging no overtime can be deemed paid until these Opt-out Fee deductions are repaid.  The FLSA also prohibits deductions unless they are voluntary and the employer derives no benefit from the deduction.  Here, Plaintiffs contend the deductions are involuntary and benefit the County by defraying its labor costs.  Finally, the FLSA requires overtime rates to be calculated on a pre-deduction basis. 29 C.F.R. § 531.37(b)., David E. Mastagni argues before the Ninth Circuit Court of Appeals in Anthony Sanders, et al. v. County of Ventura, 2023
  • On May 5, 2020, the California Supreme Court heard oral arguments via video-conference in the much anticipated appeal over whether promised pension benefits are vested rights protected by the U.S. and California Contracts Clauses. (Alameda County Deputy Sheriffs' Association et al. v. Alameda County Employees' Retirement Association et al., S247095) Arguing on behalf of the Alameda County Deputy Sheriffs’ Association, David E. Mastagni explained how the County of Alameda recruited deputies by promising that if the deputies devoted 30 years of service in law enforcement, the County would provide them substantial deferred compensation in the form of a pension calculated as a percentage of their "compensation earnable." The County promised to apply the definition of "compensation earnable" that was established by a court approved settlement order in 1999. In 2012, Governor Brown signed into law PEPRA, which reduced this promised pension formula by over 15%. David detailed how the Contracts Clause was enacted after the Revolutionary War to protect Americans from legislatures changing the rules after the fact and to promote stability of contracts. He argued the federal and California Contracts Clauses are as relevant now as they were in the eighteenth and nineteenth centuries, as shifting political opinions and policy goals can make it seem attractive to raid pre-existing, long-term financial obligations whenever the state wants to spend money on priorities., David E. Mastagni Argues Over Vested Pension Rights Before The California Supreme Court, Public Employees, 2020
