Ahhh. Yes, para. a.(3) does tack a limit on the power. Thanks for bringing that up.
It’s a(1) that is the problem “conditions that the Governor deems proper.” As in any exercise of a grant of discretion, exercise of discretion must be reasonable, i.e. for valid stated reasons. Avoiding deportation as a criminal is not a valid stated reason.
Still seems convoluted. It doesn’t surprise me that California’s constitution would read like a communist one; the supreme court there did not regard it as an “abuse of power” for to declare California a “sanctuary state” in violation of US Constitution Article IV’s Guarantee Clause (the same clause also gives the federal government the power to “guarantee to the states a republican form of government”; a socialist form of government is antithetical to this and could legally be removed by the federal government).
