Basically on the Constitution/laws/regs, I agree with you again. As far as Eyrei's letter goes, let me quote a bit of it first:
Finally, the republic is in dire need of workers to build railroads. I request that each province provide two worker units within the next ten turns if at all possible to aid in this task. Chondote will be queued to build four workers in succession to begin construction of national railway stretching from Thebes to PDX, and then south to Fox's Nest.
Key word in the paragraph is request. He did not post an order or demand compliance. He wrote a letter to the Gov'nas asking if they would help with the railway system. In his last post to the letter, he stated that the new workers would stay in the Province they were created in. I don't see the need for a poll in this situation. There was a quick turn around time for a decision by the governors requested in the letter (within 10 turns) which means in one turn chat. This wasn't really the proper way for the Domestic Leader to handle his plan, but as I stated before, this was only a request. (Which, as a Governor, I originally complied with.)
And you are right about there not being enough time to approach this situation with a valid poll. And you are right that the laws/regs should cover these kinds of situations. And you are right about these conversations belonging in both threads.
So I guess I'll keep on replying.
