[Contemporary Docs] "An Act for the more effectuall Suppressions of Piracy"
Perhaps most important, however, is the formal recognition that "Persons committing Piracies Robberies and Felonies on the Seas in or neare the East and West Indies and in Places very remote cannot be brought to condign Punishment without great Trouble" all the way back in the courts of England." As a result, "all Piracies Felonies and Robberies committed in or upon the Sea, or in any Haven River Creeke or Place where the Admirall or Admiralls have Power Authority or Jurisdiction may be examined inquired of tryed heard and determined and adjudged according to the Directions of this Act in any Place at Sea or upon the Land in any of His Majesties Islands Plantations Colonies Dominions Forts of Factories." This essentially allowed the court to follow the crime and would be the final death knell for English piracy in the Atlantic and Indian Oceans.
Interestingly, the document also seeks to address the root causes of piracy - which Daniel Defoe and others had long pointed to as a necessity in dealing with the practice. While the treatment of men aboard ship was still not addressed, the Act does install a punishment for merchants who abandon their sailors (whether it be because they found cheaper labor, or because they simply did not want to pay their wages).
