The U.S. Supreme Court on Monday refused to hear a Michigan man’s attempt to challenge the use of full body scanners at airports.

The appeal was filed by Jonathan Corbett, who challenged the Transpiration Security Administration’s use of the scanners as well as pat downs at airport security checkpoints.

Corbett claimed the TSA’s screening techniques violate travelers’ protection against illegal searches under the Fourth Amendment of the U.S. Constitution.

Corbett was appealing previous rulings court rulings refusing to hear his case.

The enhanced pat downs and full body scans went into effect in October 2010. When the technology was first released the TSA scanned entire bodies, creating what many called a “naked” image.

If a person refused to go through the scanner, TSA agents were allowed to use their hands to feel around traveler’s breasts and genitalia. 

In July 2011, the TSA released new software that eliminated the image of an actual passenger and replaced it with a generic outline in an effort to enhance the privacy of travelers.
