How to investigate civil liability for sending short messages by mistake

Usually not. But it depends on what the situation is.

If you have caused certain economic losses by sending short messages to the wrong recipients, you can pursue the responsibility through civil litigation. You can send a letter of claim to the other party, or file a civil lawsuit to ask the other party to compensate you for your economic losses.

Before that, I suggest you try to solve the problem through negotiation. You can communicate with the other party, explain the situation and ask for compensation for your own economic losses, or reach an agreement with the other party to avoid legal disputes.

If no settlement can be reached through consultation, a civil lawsuit can be brought to the local people's court. In the process of litigation, you need to provide enough evidence to prove that you suffered economic losses because of sending short messages by mistake, and at the same time, you need to prove that the losses were caused by the other party's fault.

It should be noted that the law does not clearly stipulate the responsibility for sending text messages by mistake, so the specific amount and method of compensation may need to be determined according to the circumstances of specific cases. I suggest you consult a professional lawyer for more detailed legal advice.
