The product authorization letter has expired, and the leader asked PS to change the date. This is illegal. If it is discovered, the consequences will be determined according to the specific circumstances.

First of all, it is illegal. After the product authorization expires, the representative no longer has the corresponding rights. If discovered, there will be different consequences depending on the specific situation, such as:

1. Using a forged authorization If a person uses a forged letter of authorization to fraudulently win a bid, the bid will be invalid;

2. If the act of forging a letter of authorization causes losses, compensation must be made in accordance with the law;

3. Forging a letter of authorization constitutes a crime Those who commit illegal acts will be held criminally responsible in accordance with the law.

So the specific consequences depend on the behavior of using a forged power of attorney. A power of attorney is a power prepared by the client and given to a person he trusts - to make financial decisions for him when he has mental or health problems that prevent him from taking care of his personal finances, such as Buy and sell properties, make bank deposits, pay taxes and submit other documents. The power of attorney can take effect immediately, or it can specify that it will take effect only after an incident occurs and will last until the death of the person concerned. If no accident occurs, the parties involved can still take charge of their own finances. There is a legal person authorization letter, a power of attorney, etc.
