It is my understanding that more legislation was passed than was acted upon, given Canal Mania and financial bubbles etc. The routes were surveyed to enable the construction of a canal from A to B, and Parliament was persuaded to pass an act specific to that route, with the historical equivalent of compuslory purchase orders, or the right to serve such orders upon the hapless landowners. Then the canal was never built. Is there any case where those orders still hold some legal water? Could anyone direct me to resources or experts who could help me understand these issues better? Many thanks!
