can counties nullify state laws?
You can only nullify a law to the extent that you can protect people from it.
I imagine it depends on the state constitution.
No. State laws would make no sense then.
By and large, no. But they could if the state legislature starts to meddle into an area that has been specifically delegated to counties. Keep in mind that unlike the federal government, within states the powers are delegated down as opposed to up.
I ask because I have a cousin-in-law running for Parish President. I don’t know what a person can do on the local level besides tax and spend and beg for state funds. How could this office go about making a parish/county more free?
It depends on what the parish is allowed to legislate independent of the state laws. Maybe local tax rates, or certain ordinances?
Many local governments have needless, crony-filled agencies that could be eliminated or at the very least, downsized. I dont know what the situations is like there in Louisiana, but here in Ohio the local governments own large tracts of unused, undeveloped land that could be sold.
