Narrative:

I was working the R46 position combined at R47; with a cpc d-side. The traffic volume at my sector was low; and there was a significant (more than 50% coverage) of weather in the airspace. I am one of the feeder sectors for the high altitude sectors (sitting behind me). The high altitude sector was extremely busy; with an extensive amount of weather and airplanes.the controller in charge was sitting next to him watching him work traffic. I overheard cpc saying; 'we need to slow this down; this is dangerous; and there's too much weather. We need this ground stopped.' since I was working his feeder sector; I called palm beach and miami and asked for a ground stop. Miami and palm beach complied. I turned around and told controller in charge that I ground stopped everything. He was busy engaged at R65; helping. A few minutes later; traffic management unit called controller in charge and asked why everything had been ground stopped. When he responded; they walked over and traffic management unit came in the area to argue why we can't ground stop traffic for safety; and how it wasn't dangerous in the first place.while cpc was still struggling to come out of the overloaded situation at R65/64/68 sector; traffic management unit called miami and palm beach and resumed departures; without coordinating this with me at the sector; or with cpc.a few hours later; I asked flm what I can do; and he said that we should do a report; but that he wouldn't initiate it. So [this report] is my only recourse. I believe that traffic management unit should not be able to coordinate restrictions that are less restrictive then what the sector is asking; without the sector's permission. In this case; I asked for a ground stop because I felt the situation was unsafe; by removing the ground stop without coordinating with me; they could have put sector 65 in an even more unsafe situation.
