Following in the footsteps of a landmark case that was recently won in Pennsylvania’s Supreme Court, Michigan lawmakers are advancing sweeping legislation of their own that is designed to prevent state law enforcement and conservation officers from conducting warrantless searches on private property.
Leading the charge is state Rep. David Martin (R-Davison) whose House Bill 6128 was approved by the Michigan House Judiciary Committee two weeks ago on September 23rd. Inside the proposal is legislation that explicitly aims to block state agencies from relying on the century-old federal "open fields" doctrine, a legal loophole that property rights advocates argue has been heavily abused.
“The government shouldn’t get a free pass to wander onto your land and search it just because there isn’t a house sitting on that particular piece of ground,” Rep. Martin said following the bill's committee approval. “Private property is private property.”

Under federal constitutional law, the Fourth Amendment’s protection against unreasonable searches and seizures is strictly applied to an individual's home and the immediate surrounding property, legally referred to as the curtilage. However, under the federal "open fields" doctrine established by the U.S. Supreme Court, open outdoor areas, even those that might be gated, locked, or clearly posted with "No Trespassing" signs, do not carry the same expectation of privacy.
In Michigan, this doctrine has allowed officers from the Department of Natural Resources (DNR) and the Department of Environment, Great Lakes, and Energy (EGLE) to routinely enter private rural acreage without a warrant. Officials frequently use this access to monitor compliance, inspect land use, and check for hunting violations like illegal animal baiting or poaching.
Landowners and hunters have long complained about finding game wardens roaming their properties, tracking their movements, or discovering state-owned trail cameras hidden on their land without their consent. Rep. Martin and other proponents argue that the current practice constitutes severe government overreach that violates the spirit of both the Fourth Amendment and Article I, Section 11 of the Michigan Constitution.
This new bill represents an expansion of a multi-year effort by House Republicans to curb these types of warrantless entries. In November 2025, the Michigan House successfully passed House Bills 4073 and 4421 in a bipartisan 63–37 vote, which specifically targeted DNR and EGLE agents.
Rep. Martin’s latest stab at legislation broadens that scope, applying the warrant requirement across all state agencies and law enforcement entities. The proposed law does, however, maintain critical carve-outs for emergencies, as it should. State officials would still retain the right to enter private land without a warrant during hot pursuits of suspects, life-threatening emergencies, or instances where evidence is facing immediate destruction.
The legislation has set off a longstanding debate between property rights groups and resource protection officials.
DNR leadership and conservation groups have expressed strong opposition to the restrictions, pointing to the fact that roughly 78% of Michigan’s hunting land is privately owned. Critics argue that forcing game wardens to secure a search warrant or direct owner consent for routine checks would severely hinder wildlife protection efforts, drain judicial resources, and cause paralyzing delays during time-sensitive poaching investigations.
All of which are seemingly fair points in practice. For the time being, House Bill 6128 is continuing its journey, and is set to hit the House floor for additional consideration.
