Interesting topic to explore, and some of it might come down to terminology, and might be different from one country to another even within Europe. Perhaps we are using different meanings for the word "dispatcher".
If you look at the rule book used in Britain, in the module "Station duties and train dispatch on ERTMS lines" (see
http://www.rgsonline.co.uk/Rule_Book/Ru ... ss%201.pdf" onclick="window.open(this.href);return false;), the dispatcher on the platform gives a ‘station work complete’ and ‘train safety check complete’ signal (3.1) and then a 'ready to start' signal (3.3). Nevertheless, 3.3 also instructs the driver, "If you receive the ‘ready-to-start’ signal before you have an authority to clear the platform, you must not move your train unless the signaller gives you permission to do so." In my mind this separates the duties of dispatcher (who gives the 'station work complete', 'train safety check complete' and 'ready to start' signals, thus informing the driver that there is no reason why he cannot proceed) and the signaller (who gives the actual authority to proceed into the next section. He might not give that authority even though the dispatcher has cleared the train to depart).
In a different module ("Station duties and train dispatch",
http://www.rgsonline.co.uk/Rule_Book/Ru ... ss%203.pdf" onclick="window.open(this.href);return false;), 3.4 does instruct the dispatcher to check that the starting signal is off before giving the 'ready to start' signal. However in 3.3 the driver is instructed, "If you receive the ‘ready-to-start’ signal [from the dispatcher] and the platform starting signal is at danger, you must not move your train towards the signal to wait for it to show a proceed aspect, unless the signaller gives you permission to do so" (3.3). This once again separates the duties of dispatcher and signaller, and specifically states that the dispatcher's 'ready to start' signal does not give the driver authority to proceed; only the signaller can give that authority. The dispatcher is supposed to have checked, but the rules allow for her/him not having done so and make it clear who has the actual authority to authorise the driver to proceed. I suppose one could also imagine a case where the dispatcher has checked that the fixed signal is off, gives the 'ready to start' signal, the train is just about to move and suddenly the fixed signal is reversed to a danger aspect. In that case clearly it is the signaller, not the dispatcher, who the driver obeys.
In South Africa (which admittedly is not in Europe), 27.4 in the driver's Module 1 "Train Working Rules" states, "A driver, before starting a train, must obtain the 'train may depart' signal [from the dispatcher] and satisfy himself that... the line ahead is clear and that fixed signals, where provided and applicable are at 'all right' or 'proceed'. When proceeding on a single line, other than where non-token working is in operation, a driver must ensure before departing that he holds the correct token for the section ahead". As with the British one, it makes the point that the authority to proceed into the next section is not given by the dispatcher but by the signaller controlling the fixed signals, or by possession of the token where applicable.
South Africa also has that distinction which you mention between a station and a halt. The former generally has at least one passing loop and, at least before the days of Centralised Traffic Control, was manned. The latter has no passing loop and was usually unmanned.
