Gov. Doug Burgum signed four bills into law Thursday afternoon. The bills all have ties to the Dakota Access pipeline protests.

House Bill 1293 expands the scope of criminal trespass under state law, but reduces the offense to a $250 citation rather than criminal charges.

House Bill 1304 makes it a misdemeanor to wear a mask or hood when committing a crime.

House Bill 1426 increases penalties for riot offenses. It allows prosecutors to charge those who take part in a riot in a manner consistent with the potential for actual harm to health safety and well-being.

Senate Bill 2302 allows the Attorney General to appoint ad hoc special agents. An example of this would be an out-of-state officer who comes to North Dakota responding to a request for assistance.

All four bills have emergency clauses that make them effective immediately.
