I tested this in a new folder for the patch and pack where my sim, living in Stonestreet Apartments #3 in Grim's Quarry, had enacted the Modern Development in Grims's Quarry, already. They voted for a repeal of the policy, and gathered signatures asking sims from the neighbourhood as well as the Evergreen Harbour world and other worlds. They got the signatures, with a little animation of signing a clipboard, but the number/tally did not reflect this, but stayed at 0/5 no matter who and how many sims they asked.
I had travelled in, and reloaded, this save a number of times, so tried in a new folder and save to see if that made a difference: placed a sim in The Shipping Views in Port Promise, enacted Green Initiative in Port Promise, stayed in the neighbourhood (no travel screens), repealed it directly, and got the signatures to count when trying to.
But when checking this result by reloading the save from the save point right after the repeal was voted for, and then use CAS and travel within the world as well as reload; I still got the signatures to count.
I also tried to have a week go by after having enacted the Green Initiative, and then try to repeal it, with travelling and reloading both before and after the repeal was requested; but still got the signatures to count.
I am not sure what made them not count in the first save, but have it ready to send if necessary.
