Since the Senate of the Roman People This is a very interesting statement, especially with "What will have been and will be necessary for other rites and what will have to be avoided or prescribed on that day, (will be) in accordance with what will be decided concerning these things by the senate of the Roman people" later in the text. This suggests that they are not responding to the final decree of the senate, but rather to a preliminary decree about consulting Augustus as to the appropriate honors. Note that Lucius died in southern France on August 20, and this decree is passed less than a month later. In the end we know that the senate did indeed order public sacrifices to Lucius' Manes to be offered every year, and that the decree in honor of Gaius Caesar suggests that other honors were passed as well.
