You are in the middle of an essay, a bachelor’s thesis or a master’s thesis and the pressure is high. The fear of making a mistake in your academic writing is real, and it has a name: plagiarism. The consequences of plagiarism are not only academic. They can end your studies, cost you your degree and, in some countries, even lead to fines.
At Mimir Mentor we know how important clarity and certainty are in this process. So here we set out precisely and directly what a plagiarism case really leads to, how the procedure usually runs at universities and how you can protect yourself actively and efficiently.
Important: The consequences of plagiarism can range from a simple reprimand through to expulsion or even the retrospective withdrawal of an academic degree. Every form of unattributed use of someone else’s intellectual work counts as academic misconduct.
What exactly are the consequences of plagiarism at university?
The consequences of plagiarism fall into three levels: assessment-related, disciplinary and legal. Your institution treats plagiarism primarily as an attempt to deceive under its examination or academic misconduct regulations.
If an examiner or the institution’s own plagiarism check finds an inadmissible borrowing, the first and most immediate consequence is:
- Failing the assessment: Your work (essay, bachelor’s thesis, master’s thesis) is normally recorded as a fail.
- An attempt used up: In systems with a limited number of attempts, as is common in Germany, that attempt counts as used and you may have only one or two resits left.
This consequence already applies to smaller but relevant plagiarism findings, even if you “only” failed to attribute a single paragraph.
2. Disciplinary consequences (your studies)
For serious or repeated plagiarism, the academic misconduct panel takes a harder line. Students are usually invited to a hearing before any decision is made.
| Severity | Possible disciplinary measures | What it means |
|---|---|---|
| Minor | Written warning or reprimand | An official record of the misconduct by the institution. |
| Moderate | Exclusion from teaching | You are barred from attending certain seminars or modules for a period. |
| Serious | Expulsion | The institution ends your studies. Depending on the regulations that apply, this can also bar you from continuing the same programme at another institution. |
| Extreme | Retrospective revocation of the degree | If the degree (for example a master’s) has already been awarded, the institution can withdraw it after the event, and courts can review that decision. In many systems there is no time limit on this. |
3. Legal consequences (the law)
Plagiarism and copyright infringement are different concepts, although a case can involve both. Academic attribution rules apply even to material that is not protected by copyright. Legal consequences depend on the material and the jurisdiction.
- Fines and financial penalties: In some jurisdictions the awarding institution can impose a financial penalty for deliberate deception; in the German state of North Rhine-Westphalia, for example, fines can reach €50,000. Independently of that, the original author can bring a civil claim for copyright infringement and demand damages, and serious infringements can also be prosecuted as a criminal offence.
- Using a degree you are not entitled to: Continuing to use an academic title obtained through plagiarism is a criminal offence in some countries and can carry a fine.
The procedure: how does a university establish plagiarism?
Want to know what happens once plagiarism is suspected? At most institutions the procedure follows a similar course:
1. Suspicion of plagiarism
The suspicion is raised either by the institution’s plagiarism detection software (for example Turnitin or Mimir Mentor) or by the examiner or reviewer. Passages are found that match published sources (the web, databases, other theses).
2. Expert report and your response
The examiner writes a formal report listing and assessing the plagiarised passages in detail (extent, relevance). You are then given a hearing and the opportunity to respond and set out your view (for example that it was an unintentional error).
3. The panel’s decision
The responsible panel weighs up the report and your response. It decides whether there was an attempt to deceive and how serious the plagiarism is.
| Assessment criterion | Effect on the consequence |
|---|---|
| Extent of the plagiarism | The larger the share of plagiarised text, the more serious the case. |
| Relevance of the passage | Were central results plagiarised, or only unimportant filler passages? |
| Intention to deceive | Is it a technical error (incorrect citation) or a deliberate concealment of the source? |
| Repeat case | Has plagiarism already been established in earlier assessments? |
If it comes to that: Use the hearing. A technical error (for example missing quotation marks) is still a defect, but it is judged more leniently than the deliberate takeover of whole sections.
Before the hearing, compare every flagged passage with your notes and drafts, check your institution’s regulations for your rights (for example to see the report and to bring a support person), and ask your student advisory service for help. How such procedures end in prominent cases is shown in our article on famous plagiarism cases; for doctoral candidates, see plagiarism in a doctoral thesis.
The Mimir Mentor plagiarism check uses up-to-date AI technology to check your text not only against millions of sources but also for semantic overlap. That way you find potential plagiarism before you submit and can make corrections safely, before your institution finds it.
Which types of plagiarism are punished most severely?
The consequences are not the same for every type of plagiarism. Panels focus on the intention to deceive and on the extent of the borrowing.
Copy-and-paste plagiarism versus paraphrasing plagiarism
| Type of plagiarism | Example | How the severity is judged |
|---|---|---|
| Copy-and-paste plagiarism | Word-for-word, unattributed takeover of whole paragraphs. | Strong intention to deceive; often classed as serious. |
| Paraphrasing plagiarism | The idea and structure are taken over but reworded slightly in your own words (without a source). | Often unintentional (the most common error). On a large scale it can still be treated as serious deception. |
| Complete plagiarism | Submitting an entire piece of someone else’s work (ghostwriting, or a whole paper copied from the internet). | Extremely serious. Can lead to serious sanctions, including expulsion, depending on the applicable rules. |
| Self-plagiarism | Reusing your own already assessed text without a citation or attribution. | Usually judged more leniently than plagiarising others, but still a breach of the requirement that the work be your own. |
The bottom line: Complete plagiarism or copy-and-paste plagiarism in a central argument of a thesis will almost certainly lead to a fail and can result in expulsion. Sloppy citation (technical errors) is treated more leniently, but it is still a defect.

How do you avoid the harshest consequences? Your action plan
The best protection against the consequences of plagiarism is certainty while you write. Mimir Mentor helps you find unintentional errors before you submit, so they do not turn into a misconduct case.
1. Establish clean citation practice
Every single piece of information that is not your own thought or general knowledge needs a citation.
- Direct quotation: Use quotation marks and give the source with the page number.
- Indirect quotation (paraphrase): Restate the other person’s thought completely in your own words and give the source. Depending on the citation style, a page number is recommended or required.
2. Use a plagiarism check before you submit
Your institution checks you, but Mimir Mentor checks for you.
- Upload your text: Upload your draft to the Mimir Mentor plagiarism check.
- Detailed report: You receive a colour-coded report showing every match, every potential paraphrase and the matching sources.
- Make corrections: You can edit the passages found straight away, cite them properly or reword them, before your examiner ever sees the work.
Important: The plagiarism score is not what decides the case. What decides it is whether the matches found are correctly cited and attributed. Mimir Mentor helps you verify that.
Mimir Mentor is GDPR-compliant, with servers in the European Union. Your document is deleted after 30 days at the latest and is never added to a public database. More than 70,000 students already use the platform.

FAQ: common questions about the consequences of plagiarism
Here we answer the most important questions so that you know where you stand.
-
Can plagiarism lead to expulsion?
Yes. For serious or repeated attempts to deceive, particularly in a thesis, the academic misconduct panel can decide on expulsion. Depending on the regulations that apply, this can also bar you from continuing the same programme elsewhere.
-
Can a degree be revoked after the event?
Yes. If plagiarism is established in a piece of work that has already been completed (for example a master’s thesis or a doctoral thesis), the institution can withdraw the degree retrospectively, and courts can review that decision. In many systems there is no time limit on this.
-
Does it matter whether the plagiarism was deliberate or accidental?
How severe the consequence is depends heavily on the intention to deceive. An accidental error (for example missing quotation marks) is usually penalised more leniently, often with a fail, than a deliberate concealment of sources, which can lead to disciplinary consequences such as expulsion.
-
Can I be fined for plagiarism?
In some jurisdictions, yes. Alongside failing the assessment, the awarding institution may be able to impose a financial penalty, and the original author can bring a civil claim against you for copyright infringement. The rules and amounts differ from country to country.
-
Is there a permitted percentage of plagiarism?
No, there is no permitted percentage. Every unattributed takeover of someone else’s ideas or text is a breach. The percentage shown by plagiarism tools is only an indicator of matches, not of plagiarism itself.
