Since you asked, I thought it best to look this up. It's more difficult than you might think! The legislation plainly says that there must be three clear days, but does not explain what is a clear day. In practice, it has long been interpreted, on the basis of a ruling in R v Herefordshire Justices (1820) as meaning weekdays excluding the day a document becomes available and the day on which the meeting takes place. This was supported in R v Swansea City Council ex parte Elitestone Ltd (1993). Now we get down to what is a weekday? "Knowles on Local Authority Meetings" says that it should not include Saturdays or Sundays. It is widely agreed that it should not include public holidays. At one time, it could have been said that Sunday was the only day on which there were restrictions concerning work, and so every other day was a weekday. Nowadays, most people would think that weekdays are Monday to Friday. If the clerk is not publishing the agenda and supporting documents, then there is a strong argument that only days when the council office is open for inspection of documents count as clear days. Unfortunately for your hope of ending pedantry, there is no definitive answer. The statutes do not provide one and there is nothing in case law. You could obtain a ruling by taking a council to the High Court over the issue, but with fees starting at around £10,000 you probably wouldn't choose to do that. If you would like to end the debate, I suggest that you propose a change to your council's standing orders to say that for the purpose of calculating clear days Saturdays (optionally), Sundays and public holidays should be excluded. The council can vote on this and agree what definition to use. Once it is part of standing orders, there is no further need for discussion. Sorry I can't do better than that!
