Legal basis:
1. Provisions of Public Security Organs on Handling Criminal Cases Article 175 After accepting a case, if a public security organ considers that the criminal facts that need to be investigated for criminal responsibility belong to its own jurisdiction, it shall file a case with the approval of the person in charge of the public security organ at or above the county level; If it is considered that there are no criminal facts, or the criminal facts are obviously minor and need not be investigated for criminal responsibility, or there are other circumstances in which criminal responsibility is not investigated according to law, the case shall not be filed with the approval of the person in charge of the public security organ at or above the county level.
If a complainant decides not to file a case, the public security organ shall make a notice of not filing a case and serve it on the complainant within three days.
Article 187 A public security organ shall promptly investigate a criminal case that has been put on file, and comprehensively and objectively collect and obtain evidence of the criminal suspect's guilt or innocence, light or heavy crime.
Two. Interpretation of the Supreme People's Court and the Supreme People's Procuratorate on Several Issues Concerning the Specific Application of Laws in Handling Criminal Cases of Impairment of Credit Card Management (Fa Shi [2009]19);
Article 6 If a cardholder overdraws beyond the prescribed limit or time limit for the purpose of illegal possession, and fails to return it for more than three months after being repeatedly urged by the issuing bank, it shall be deemed as "malicious overdraft" as stipulated in Article 196 of the Criminal Law.
In any of the following circumstances, it shall be deemed as "for the purpose of illegal possession" as stipulated in the second paragraph of Article 196th of the Criminal Law:
(a) knowing that there is no repayment ability and a large amount of overdraft can not be returned;
(two) squandering overdraft funds, unable to return;
(3) Escaping after overdraft, changing contact information and avoiding bank collection;
(4) evading or transferring funds, concealing property or evading repayment;
(five) the use of overdraft funds for illegal and criminal activities;
(six) other acts of illegal possession of funds and refusal to return them.
Malicious overdraft, the amount of which is more than 6,543.8+0,000 yuan but less than 6,543.8+0,000 yuan, shall be deemed as "a large amount" as stipulated in Article 196 of the Criminal Law; If the amount is more than 654.38+10,000 yuan and less than 1 10,000 yuan, it shall be deemed as "huge amount" as stipulated in Article 196 of the Criminal Law; If the amount is more than 6,543.8+0,000 yuan, it shall be deemed as "extremely huge amount" as stipulated in Article 196 of the Criminal Law.
The amount of malicious overdraft refers to the amount that the cardholder refuses to return or has not returned under the conditions stipulated in the first paragraph. Does not include compound interest, late fees, handling fees and other fees charged by the issuing bank.
Malicious overdraft should be investigated for criminal responsibility. However, if all the overdraft interest has been repaid after the public security organ files the case but before the announcement of the judgment of the people's court, the punishment may be given a lighter punishment, and if the circumstances are minor, the punishment may be exempted. If the amount of malicious overdraft is large, and all overdraft interest has been repaid before the public security organ files a case, and the circumstances are obviously minor, criminal responsibility may not be investigated according to law.
