Implementing the agreement required a change to the charter, however. Independent lotholder Simon Wolf successfully petitioned Senator John James Ingalls (R-Kansas) to introduce legislation in the 49th United States Congress to amend the PHC charter to reaffirm the rights of lotholders. The bill was favorably reported out of the Senate Committee on the District of Columbia on March 30, and passed the full Senate on June 17. The legislation (S. 1187) amended the cemetery's charter so that the cemetery corporation was not permitted to hold more than and not less than , and affirmed that the core of the cemetery could never be sold or used for any purpose other than a burial ground. The bill also affirmed the right of all lotholders (not just those associated with Concordia Church or the German Evangelical Church Society) to vote at annual meetings and hold office, provided new rules for managing the annual meeting and casting votes, directed the cemetery to use its income solely for the benefit of the burying ground, and expanded the board of directors to nine directors (each of which had to be elected annually by a majority of lotholders). Although the Commissioners of the District of Columbia initially did not oppose the bill, on June 26 they asked the Senate to table the bill and decline to send it to the United States House of Representatives for action. The city was contemplating extending North Capitol Street past Boundary Avenue (now Florida Avenue) to the United States Soldiers' Home (about double its existing length), and the provision of the bill which prevented use of the Prospect Hill Cemetery grounds for any purpose other than a cemetery interfered with the street's proposed route. The Senate, however, did not table the bill and the House approved it unaltered.
