Amicus Curiae Support:

Horvitz & Levy regularly prepares amicus briefs to inform appellate courts about how their decisions will affect individuals and businesses who are not parties to the case. Our amicus briefs advance arguments to move or clarify the law in ways favorable to our clients, for example, by explaining how other jurisdictions handle similar issues more fairly or efficiently.

Trial Consultation:

In cases that are of exceptionally high value to our clients, either because of the liability exposure in the individual matter or because of recurring institutional issues, Horvitz & Levy works in the federal and state trial courts, laying the foundation for an appeal before a notice of appeal is filed. We consult with trial lawyers with an eye toward preserving important legal issues for appeal. We draft critical pre-trial motions, like motions for summary judgment and motions in limine, in an effort to secure a victory in the trial court before a verdict is returned. And if an adverse verdict is returned, we often draft important post-trial motions to obtain any possible relief from the trial judge.
