“The eyes don’t lie” or can they? The future of the HGN test in PA

“The eyes don’t lie” or can they?

The McShane Firm attorneys acted through the Pennsylvania Association of Drunk Driving Defense Attorneys (PADDDA) as amicus curiae in filing an amicus brief with the Supreme Court of Pennsylvania in the case of Commonwealth v. Weaver.

The certified question by the Pennsylvania Supreme Court in Commonwealth v. Weaver:

Whether horizontal gaze nystagmus (HGN) field sobriety test results, which have been deemed to be scientific evidence under Pennsylvania precedent, are [in]admissible at a suppression hearing for lack of probable cause to arrest for driving under the influence absent any admission of foundation evidence presented to show that the HGN test is generally accepted in the scientific community?

Here is the full appendix: http://www.paddda.com/wp-content/uploads/6-12-14-Weaver-Full-Appendix.pdf


The structure of the brief was brainstormed and written by Attorney Justin J. McShane of The McShane Firm as well as Attorney TC Tanski also of The McShane Firm, and Richard Roberts, Senior Legal Intern at The McShane Firm.

We all wish Dave Erhard of Gettysburg, who has the merits brief on behalf of the motorist accused, the very very best in his homestretch preparation on his merits brief. I am confident that it will be excellent.
