The Legal Center is the advocate for small businesses in the courts. We tell judges how the decision they make, in a given case, will impact small businesses nationwide. Importantly, we only initiate lawsuits and file amicus (“friend-of-the-court”) briefs in precedent-setting cases. That means we go to court in those cases that will impact many small business owners.
