When the United States Supreme Court, along with the rest of the new Federal Government moved, in 1791, from New York City to the nation's temporary capital in Philadelphia, Dallas was appointed the Supreme Court's first unofficial, and unpaid, Supreme Court Reporter. (Court reporters in that age received no salary, but were expected to profit from the publication and sale of their compiled decisions.) Dallas continued to collect and publish Pennsylvania decisions in a second volume of his Reports. When the Supreme Court began hearing cases, he added those cases to his reports, starting towards the end of the second volume, "2 Dallas Reports", with "West v. Barnes" (1791). Dallas went on to publish a total of four volumes of decisions during his tenure as Reporter.
