The Michigan House has approved a resolution to amend the state constitution requiring law enforcement to obtain a search warrant before looking through electronic data or communications.
The House on Thursday passed the resolution 107-1 to include electronic communications under a section of the constitution protecting against unreasonable search and seizure.
It would still require passage by a two-thirds majority of the Senate as well as voter approval.
If the Senate OKs the measure, it could go before voters on the November ballot.
Resolution sponsor Rep. Jim Runestad, a Republican from White Lake, says the amendment is necessary to prevent the erosion of citizens' rights as technology advances.
Missouri approved a similar measure in 2014 with voter approval.
