The vote came after Rep. Russell Pearce (R-Mesa) diluted some provisions to make it more acceptable to the business community. That includes an escape clause that says companies cannot be penalized if they comply with state and federal hiring laws.

The legislation subjects first-time offenders to fines of at least $2,000 per undocumented worker; companies with three offenses within a year would pay a minimum of $6,000 per offense, with a mandatory year in jail for violators.

One part of the law essentially involves someone squealing. The legislation would set up an office to take complaints about companies that do not comply with federal immigration law.
