[2-6430] Reserved judgement

If a judicial officer reserves judgment or decision on any question, that judgement or decision may be given either in open court or in the absence of the public, or reduced to writing, signed and forwarded to the registrar at the venue for the proceedings: r 36.3(1). If the judgement or decision is given by the judicial officer, it may be at the venue of the proceedings or at any other place at which the judicial officer is authorised to hear or dispose of the proceedings. If a registrar receives a judgement so forwarded, the registrar must appoint a time for the decision or judgement to be read. The registrar must give at least 24 hours notice to the parties, in writing or otherwise, of the appointed time. At that time the judgment or decision must be read by another judicial officer or the registrar, whether or not the court is sitting at that time: r 36.3(2).

A judgment or decision so given or read takes effect at that time and is as valid as if given by the judicial officer at the hearing: r 36.3(3).

The procedure authorised by r 36.2 applies to a reserved judgment or decision: r 36.3(4).

Según esto, sería "dictar sentencia", pero prefieron que un experto en leyes lo corrobore.

Sería: "Esta sentencia se dictaminó..."

Reserved judgment: (derecho procesal) sentencia retenida; se dice de la sentencia para la que el juez o jueza se ha tomado un cierto tiempo antes de pronunciarla.
Lo dejo como referencia, ya que no es mi campo, aunque parece que el contexto es el adecuado. Espero que sea de ayuda.
