A Nighttime Blood Draw on a Daytime-Only Warrant — and Why the License Revocation Still Stood

What Happened

On a December evening, a Wright County deputy responded to a rollover — a utility task vehicle on its side, pulling a trailer, with the driver still pinned inside and complaining of rib and chest pain. Firefighters pulled him out and an ambulance took him to the hospital. While that was happening, the deputy noticed two cracked-open beer cans in the cup holder, a strong odor of alcohol, and slurred speech. He started working on a warrant for a blood or urine sample.

Here's the wrinkle. The deputy was new — this was only his second search warrant application. He didn't check the box on the electronic form that flags the need for a nighttime warrant, later testifying he didn't know the box existed. He submitted the application at 8:18 p.m., a judge signed it at 8:37 p.m., and the warrant said on its face that it could be executed "between the hours of 7 a.m. and 8 p.m." The deputy, not realizing the warrant was daytime-only, waited for hospital staff and drew the blood around 9:30 p.m. The result came back over the legal limit, and the Department of Public Safety revoked the driver's license.

The Rule: Minnesota Restricts Nighttime Warrant Execution

Minnesota law doesn't let officers serve a search warrant at any hour they please. Under Minn. Stat. § 626.14, a warrant can be served only between 7 a.m. and 8 p.m. unless the judge specifically finds — based on facts in the affidavit — that a nighttime search is necessary to prevent the loss or destruction of evidence, or to protect the officers or the public. If the warrant doesn't grant that nighttime authority, an after-hours search violates the statute. Everyone in this case agreed that's exactly what happened.

Why the Violation Wasn't Enough

This is the part worth understanding. When a search violates a Minnesota statute, courts don't automatically throw out the evidence. They ask a follow-up question: was this a technical violation, or a serious one that undercut the whole point of the rule? That framework comes from a pair of 2007 Minnesota Supreme Court cases, State v. Jackson and State v. Jordan. Only serious violations — ones that "subvert the basic purpose" of the statute — call for suppression.

So what is the purpose of the nighttime rule? The Supreme Court has been specific about it. It's meant to protect people from "the indignity of being roused out of bed in the middle of the night" and, more broadly, to guard a person's "freedom from intrusion during a period of nighttime repose." In other words, it's built around the sanctity of the home at night — the sleeping household, the knock at the door in the dark.

And that's where this driver's argument ran out of road. He wasn't home in bed. He was in an emergency room being treated for crash injuries when his blood was drawn. The court held that having blood taken in a hospital during treatment simply doesn't carry the same intrusion the nighttime statute was written to prevent. Because the violation didn't subvert the statute's purpose, it was technical — and the revocation stood.

The Arguments the Driver Made — and Why They Didn't Land

Two of his points are worth calling out, because they're the natural instincts and it helps to see why they failed:

• "A blood draw is deeply invasive." True, and the court agreed a blood draw is a significant intrusion. But the nighttime statute isn't about how invasive the search is — it's about the disturbance to someone's nighttime rest and privacy. The invasiveness of a blood draw doesn't change that analysis.
• "They were an hour and a half late — that's not trivial." He pointed to an earlier case where a search just two minutes early was called "de minimis," and argued 90 minutes past the line is a different animal. The court wasn't persuaded. How far past 8 p.m. the search happened is one factor, not the deciding one. The central question stays the same: was the purpose of the statute subverted? Here, the court said no.

He also raised a constitutional argument, but didn't explain how it called for any different analysis than the statute, so the court declined to treat it separately.

What This Means for You

A nighttime-warrant defect is real and always worth investigating — but where the search happened matters enormously. The lesson running through this decision is that a § 626.14 violation is at its strongest when the search intruded on the home and someone's nighttime repose, and at its weakest when it didn't. A late blood draw in a hospital is a hard place to win that fight. A nighttime entry into a home is a very different story — which is one reason nighttime and no-knock home searches get such close scrutiny.

None of this means these challenges don't work. It means they're fact-driven. The warrant, the affidavit, the timing, the location, and what the officer actually knew at the moment of the search all feed into whether a violation is technical or serious. That's exactly the kind of detail that rewards a careful, line-by-line review of the file — and it's the kind of issue that's easy to miss without one.

Key Terms

• Implied consent / license revocation: The civil process by which the State revokes your driver's license after a DWI-related test failure — separate from the criminal case.
• Nighttime warrant (Minn. Stat. § 626.14): Special authorization a judge must grant, on stated facts, before a warrant can be executed outside 7 a.m.–8 p.m.
• Technical vs. serious violation: Minnesota's test for whether a statutory violation requires suppressing evidence. Only serious violations that subvert the statute's purpose do.
• Nighttime repose: The interest the nighttime statute protects — freedom from being disturbed at home during the night.
• Nonprecedential opinion: A court decision that can be persuasive but does not bind future courts as controlling authority.
