AB 1950 may be applied retroactively under Estrada to shorten the defendant’s period of probation if the defendant’s case is not final, even if the defendant’s probation was properly terminated before the passage of AB 1950. Thus, if a probation term is shortened to two years under amended section 1203.1, conduct that would have constituted a probation violation, but is now deemed to have occurred outside this term, may not be the basis for terminating that probation. The effect of applying AB 1950 retroactively to shorten the period of probation in these circumstances is an effect “fairly contemplated” within the legislation’s underlying purpose.
