William J. Brennan,
Ashe v. Swenson — Concurrence
“ Flexibility in the rules governing the structure of civil litigation is appropriate in order to give the parties the opportunity to shape their own private lawsuits, provided that injustice, harassment, or an undue burden on the courts does not result. Some flexibility in the structuring of criminal litigation is also desirable and consistent with our traditions. But the Double Jeopardy Clause stands as a constitutional barrier against possible tyranny by the overzealous prosecutor. ”
