Brillantes assured the public that despite the nonexistence of the source code, the machines can still work via the binary code. On early May, senatorial candidate Richard Gordon petitioned to the Supreme Court the commission to order the latter to reveal the source code to local review groups. Gordon, who authored the law mandating the automated elections, said that the commission does not have the discretion on whether or not political parties can review the source code. A few days after Gordon's petition, or exactly a week before the election, Brillantes announced that Smartmatic and Dominion signed an agreement releasing the source code, and that it would be presented to the public on May 8.

However, the Supreme Court of the Philippines issued a restraining order reverting to the two-day liquor ban after it upheld a petition by the Food and Beverage Inc. and International Wines and Spirits Association. The commission then withdrew its resolution instituting the five-day liquor ban, reverting the ban to two days as originally intended by law. Money ban In order to curb vote buying, the commission issued a resolution prohibiting bank withdrawals of more than 100,000 pesos. However, Secretary of Justice Leila de Lima expressed reservations on the constitutionality of the so-called "money ban", and the Bangko Sentral ng Pilipinas has explicitly stated that it would
