Early hours DCT Flight Routings.

Actual flightplan of an overflight.

MERIT HFD PUT EBONY N123A YAY HECKK 5400N 05000W 5600N 04000W 5700N 03000W 5600N 02000W RESNO NETKI LIPGO KONAN UL607 KOK..........

I understand that between the hour's of 0001/0520z an aircraft transiting Irish/UK airspace can request a DCT from say the above example: LIPGO-KONAN but my question is who actually 'rubber stamps' the routing? Does this relaxing of the routing down established airways continue into continental Europe?

If I understand your question correctly:

In this case, with ref. to https://www.cfmu.eurocontrol.int/RAD/1208/docs/E1_RAD_4_RADAN_NERS_EB_1_en.pdf , the NETKI DCT LIPGO DCT KONAN can be filed on a flight plan if the time (as you mentioned) requirements are met. So basically pilots wont even need requesting the DCT, it is already approved if FPL was accepted.

As a good example of "relaxing of the routing" a DK/SE Fre Route Airspace can be mentioned, Maastricht weekend DCT's.
