This system allows the High Council of Gallifrey or the Celestial Intervention Agency to control any TARDIS with a Recall Circuit whose location is known. They can force it to materialize in any Time Zone and prevent dematerialization. As with most forms of remote TARDIS navigation, use of the Remote Control drastically reduces the life span of a TARDIS's Zyton-7. Should an operator find a way to override Remote Control, the Time Lords can use Collection Beams on any dematerialized TARDIS whose location in the Vortex is known.
Circuits that allow Rassilon to override the commands of a Time Lord operator are traditionally installed on all TARDISes. These same circuits can also be controlled using the Ring of Rassilon. In a similar fashion, the original Worshipful and Ancient Law of Gallifrey serves as a "key" to the Time Lord prison asteroid, Shada. When the pages of this book are turned while within a TARDIS the book will use Remote Control to pilot a TARDIS to Shada.
