What it held
Under the CGP art. 291 route, it was reasonable to deny effect to an email notice with no acknowledgement of receipt, where the courier reported the emails had not been opened. The Court clarified the point was not proving the email was opened, but that the sender received the acknowledgement.
Why it matters
A «sent» record on its own is weak: what counts is proof that the recipient's server received the message.
Inciso 3 of article 8 of Decreto 806 de 2020 is constitutional on condition that the term it sets starts when the sender receives an acknowledgement of receipt or access by the recipient can otherwise be established. In a nullity motion the affected party's oath is not enough: the judge must weigh the whole proceeding and the evidence.
Why it matters
The constitutional anchor of the rule. Ley 2213 de 2022 wrote that condition into inciso 3.
The requirements of article 8 of Ley 2213 de 2022 are the oath, the source of the address and the evidence. Proof is free: the acknowledgement of receipt is confirmation that the message reached its destination, and may be shown by a voluntary or automatic acknowledgement, a record from authorised postal service companies or documents filed by the plaintiff. Screenshots are valid as evidence, and data messages are filed in the same format in which they were generated.
Why it matters
The leading case: a server-side acceptance record is a valid acknowledgement, and no paid postal email service is required.
Requiring an email «chain of sends» to authenticate a power of attorney is excessive formalism. The Court notes judges check the attorney's email against the Registro Nacional de Abogados.
Why it matters
The memorial reporting the notification should come from the lawyer's registered email.
Set aside a nullity an appellate court had declared because the message did not state the date of the order or when notice would be complete: that decision imposed requirements article 8 does not contain and amounted to excessive formalism.
Why it matters
Nullity attempts happen. Including those details in the message is not mandatory, but removes the argument.
A judge may not require the plaintiff to produce a delivery record or acknowledgement of receipt on pain of tacit abandonment: that demand contradicts good faith and does not follow from the statute. Notice is deemed made two business days after sending and, as a rule, the term runs from there, unless the plaintiff or the judge notices that the message was not sent successfully; actual receipt is argued in a nullity motion.
Why it matters
The court reporter tags it as unifying the criterion on inciso 3. Proof of delivery is defensive: it decides the nullity.
Sending the auto admisorio from an email other than the one in the complaint or the one recorded in the Registro Nacional de Abogados «in no way affects the notification» if actual notice was achieved; demanding additional requirements is an error.
Why it matters
Supports sending from a notifications domain on the lawyer's behalf.
Notice sent to the email listed in the defendant's RUT was valid in a non-tax proceeding. The claim that the plaintiff created that email fraudulently failed for lack of even prima facie proof; the tutela was denied.
Why it matters
Supports the RUT and the commercial registry as address sources, and shows why the notification record must be tamper-evident.
