Guest columnists Igor De Lazari, Antonio Sepulveda, and Judge Sergio Dias describe how Brazil recently addressed an issue currently before the US Supreme Court-an issue of when (and whether) a state may collect taxes on goods that originate out of state. De Lazari, Sepulveda, and Dias suggest that perhaps the issue is better resolved, as it was in Brazil, through the legislative process rather than by court decision, so as to ease what is likely to be an abrupt transition.
