Among the thousands of spectators who will flock to the New York City marathon this weekend, Daniel Brown of Sheppard, Mullin, Richter & Hampton will be marking an especially important milestone.

After his wheelchair-bound brother was forced to make way for other participants in the marathon 25 years ago, Brown, 44, brought a class action to stop the practice. On Sunday, he’ll watch his brother Alan, 48, compete in the marathon for the first time since that 1991 race. And thanks to a successful settlement in the case, this time no one can ask Alan Brown to move aside.
