[Direct answer]In principle, this will not happen, but there are exceptions. According to Article 237 of the Criminal Procedure Law of the People's Republic of China, when the second-instance people's court tries cases appealed by the defendant or his/her legal representative, attorney, or close relatives, it shall not increase the defendant's punishment, which is the principle of no increase in punishment upon appeal. However, if the people's procuratorate lodges an appeal, it is not subject to this principle. In cases of guilty plea and plea bargain, if the defendant appeals without a valid reason, the procuratorial organ may consider that he/she has changed his/her mind and the original sentencing proposal has lost its basis, and therefore lodge an appeal; once the appeal is lodged and the second-instance court changes the verdict, the punishment may be increased. Whether to appeal should be based on the reasons and risk assessment.

1. Problem background and typical scenarios

After the defendant signs the plea agreement and accepts the sentencing proposal, the court will sentence them leniently according to law. However, after the verdict, the defendant may feel that the sentence is too harsh and want to appeal for a lighter sentence. There are also cases where the defendant pleads not guilty in the first instance, but later wants to plead guilty and appeal for a lighter sentence after the verdict. In practice, there are indeed cases where defendants appeal after pleading guilty and accepting the sentencing proposal, but there have also been frequent cases of prosecutorial appeals and sentencing adjustments arising from such appeals. Appealing is a right, but appealing in the context of pleading guilty and accepting the sentencing proposal carries special risks, and careful consideration is needed.

II. Key points of contention

First, the application boundary of the appeal without increasing the sentence. Second, the triggering conditions for the procuratorial organ to file a counter-appeal. Third, whether the basis for leniency in pleading guilty and accepting the punishment is lost due to the appeal. Fourth, under what circumstances the appeal is more justified and likely to succeed.

III. Professional analysis by Henglue Lawyers

The first layer is that the principle of not imposing heavier punishment upon appeal applies: in cases where the defendant appeals, the second-instance court shall not impose heavier punishment, including not extending the term of imprisonment, not converting probation to actual imprisonment, or not imposing heavier additional punishments, etc. This provides a guarantee for the defendant to exercise the right of appeal. The second layer is that the prosecution's objection is a breakthrough point but also a risk point: if the prosecution believes that the first-instance judgment is indeed erroneous or the sentencing is disproportionately lenient, it may file an objection. In this case, the second-instance court is not subject to the restriction of not imposing heavier punishment upon appeal and may impose a heavier sentence. In cases of plea bargaining, if the defendant retracts the plea of guilty or denies the plea bargain without a valid reason, the prosecution often files an objection on this basis and argues that the original lenient sentencing proposal is no longer applicable. The third layer is the basis of leniency in plea bargaining: leniency in plea bargaining is based on the defendant's voluntary plea of guilty and acceptance of the sentencing proposal. Once the appeal negates the plea of guilty or the sentencing proposal, the lenient circumstances may be re-evaluated. In practice, the court distinguishes the reasons for appeal. Appeals based on valid reasons such as sentencing reasoning or factual determination are significantly different from simple retractions. The fourth layer is the judgment of whether there is a chance of success: if there are errors in factual determination, obviously inappropriate sentencing, procedural violations, or new evidence, the appeal is of substantive significance. If the appeal is based solely on the feeling that the sentence is too severe, not only is the chance of success low, but it may also lead to an increase in the prosecution's objection. Henglue advises that in cases of plea bargaining, a full assessment of the risk of prosecution's objection and the basis of leniency should be conducted before the appeal, and if necessary, a professional opinion should be provided by the defense attorney to avoid worsening the outcome due to an improper appeal. When handling such cases in Beijing, the court will focus on reviewing the legitimacy of the appeal reasons and the voluntariness of the plea bargain.

IV. Practical suggestions and legal basis

The first step is to review whether there are substantive issues in the determination of facts, the admissibility of evidence, the application of law, and sentencing in the first-instance trial. The second step is to assess whether the procuratorial organ may file a counter-appeal and increase the risk. The third step is to appeal in accordance with the law with legitimate reasons and submit sufficient defense opinions to avoid simply changing one's mind. The fourth step is to simultaneously put forward new mitigating circumstances and evidence during the appeal to strive for a change of the judgment or a lighter sentence. The main legal basis: Articles 15, 201, 227, and 237 of the Criminal Procedure Law of the People's Republic of China (amended and implemented in 2018) and the relevant provisions on the application of the leniency system for guilty plea and sentencing. The specific application shall be subject to the currently effective provisions.

5. Henglu Law Firm's Reminder

The three key points of pleading guilty and accepting the punishment and appealing: The defendant may appeal without having the punishment increased, but the prosecution may challenge the appeal; if the defendant retracts his/her plea without a legitimate reason, he/she may face a challenge to the appeal and lose the opportunity for leniency; it is necessary to assess the risks before appealing and only appeal when there are substantial grounds.

VI. Frequently Asked Questions

Q1: Will the appeal necessarily result in a harsher sentence?

Not necessarily. If the defendant appeals, the second-instance court may not impose a heavier punishment on him/her; only when the procuratorial organ files a counter-appeal will this restriction not apply. Whether the punishment will be increased depends on the grounds of the counter-appeal and the facts of the case.

Q2: What happens if one appeals after pleading guilty and accepting the punishment?

This may trigger an appeal by the procuratorial organ, arguing that the original sentencing proposal is no longer applicable. If the appellate court adopts the opinion of the appeal, the punishment may be increased, so it is necessary to carefully evaluate the grounds for appeal and the risks involved.

Q3: Under what circumstances is it more advisable to appeal?

When there are reasonable grounds such as factual misidentification, manifestly inappropriate sentencing, procedural violations, or new evidence, an appeal becomes more substantive and less likely to lead to adverse consequences.

Q4: Can the appeal still be withdrawn after it has been filed?

Yes. Before the second-instance judgment is pronounced, the defendant may apply to withdraw the appeal, and whether the application is granted shall be decided by the second-instance court; after the withdrawal, the first-instance judgment shall take legal effect.

Q5: What is the difference between a procuratorate's appeal and an appeal by a defendant?

The appeal is initiated by the defendant and is protected by the principle of "no heavier punishment upon appeal". The procuratorial organ initiates the counter-appeal, which is not subject to this restriction and may result in a heavier punishment. The subjects and effects of the two appeals are different. Regardless of whether it is an appeal or a counter-appeal, the second-instance court will conduct a comprehensive review of the facts and the application of the law.
