Similarity Check Policy

Similarity Check Policy

???? Similarity Screening: All manuscripts submitted to NUSALEGIS: Journal of Legal Studies are subject to similarity screening before proceeding to the peer-review or publication process. As a general editorial standard, manuscripts should have an overall similarity index of no more than 20%, subject to qualitative evaluation by the Editorial Team.

A. POLICY STATEMENT

NUSALEGIS: Journal of Legal Studies is committed to protecting academic integrity, originality, and responsible scholarly publication. For this purpose, submitted manuscripts may be examined using recognized similarity-detection software before being sent for external peer review and, where necessary, at later stages of the editorial process.

Similarity screening is intended to identify substantial textual overlap, inappropriate copying, insufficient attribution, duplicate publication, self-plagiarism, and other potential concerns relating to manuscript originality.

A similarity report is used as an editorial assessment tool and does not by itself establish that plagiarism has occurred.

B. SIMILARITY THRESHOLD

Recommended Maximum Overall Similarity

≤ 20%

Manuscripts exceeding this level may be returned for revision or further editorial assessment.

The 20% threshold is not applied mechanically. The Editorial Team will assess the nature and location of the detected similarities, the sources involved, the presence of appropriate quotation and citation, and whether the overlap represents legitimate use of legal or scholarly materials.

C. QUALITATIVE ASSESSMENT OF SIMILARITY

The Editorial Team evaluates similarity reports contextually. Particular attention may be given to the following:

Overall Similarity

The total proportion of textual similarity identified throughout the manuscript.

Single-Source Similarity

Whether a significant portion of the manuscript is derived from one particular source.

Location of Similarity

Whether overlap occurs in the main analysis, research findings, methodology, legal provisions, references, or standard terminology.

Citation and Attribution

Whether overlapping material has been appropriately quoted, paraphrased, and attributed to its source.

Nature of the Material

Special consideration may be given to statutory language, treaty provisions, judicial quotations, and other legal texts that require accurate reproduction.

Previous Work by the Authors

The journal assesses whether substantial overlap with the authors' previous publications constitutes legitimate reuse or inappropriate self-plagiarism.

D. SPECIAL CONSIDERATIONS FOR LEGAL RESEARCH

Because legal scholarship frequently requires reference to authoritative legal texts, similarity reports must be interpreted carefully. Textual overlap may legitimately arise from accurate citation or reproduction of:

  • Constitutional provisions;
  • Statutes and regulations;
  • Judicial decisions;
  • International treaties and conventions;
  • Official government documents;
  • Standard legal terminology;
  • Properly quoted scholarly materials.

Such similarities are not automatically considered plagiarism when the source is appropriately identified and the use complies with accepted scholarly and legal citation practices.

E. PLAGIARISM

Plagiarism includes the presentation of another person's words, ideas, arguments, legal analysis, research findings, data, images, or intellectual contributions as one's own without appropriate acknowledgment.

Examples may include:

Direct Plagiarism

Copying text without quotation or appropriate citation.

Mosaic Plagiarism

Combining copied phrases or ideas from multiple sources without proper acknowledgment.

Improper Paraphrasing

Closely rewriting a source without sufficient original expression or citation.

Idea Plagiarism

Using another person's original argument or intellectual contribution without acknowledgment.

Self-Plagiarism

Substantial reuse of an author's previously published material without appropriate citation or disclosure.

Duplicate Publication

Republishing substantially the same scholarly work without appropriate disclosure.

F. SIMILARITY SCREENING PROCEDURE

1. Submission 2. Similarity Check 3. Editorial Assessment 4. Decision 5. Peer Review
  1. The manuscript is submitted through the NUSALEGIS Online Journal System.
  2. The Editorial Team conducts an initial technical and editorial screening.
  3. The manuscript may be processed using recognized similarity-detection software.
  4. The similarity report is reviewed qualitatively by the Editorial Team.
  5. The editor determines whether the manuscript may proceed to peer review, requires revision, or should be rejected.
  6. Where necessary, a manuscript may be screened again after revision or before final publication.

G. EDITORIAL ACTION BASED ON THE REPORT

Similarity Result Editorial Assessment Possible Action
≤ 20% Generally acceptable, subject to qualitative review. Proceed to the next editorial stage if no serious overlap is identified.
> 20% Requires additional editorial examination. Return for revision, request clarification, or proceed if overlap is legitimately explained.
Serious Unattributed Overlap Potential plagiarism regardless of total percentage. Manuscript may be rejected or investigated further.

Important: A manuscript with a similarity score below 20% may still be rejected if serious plagiarism is identified, while a manuscript slightly above 20% may be considered further where the overlap consists primarily of properly cited legal texts, quotations, references, or other legitimate material.

H. RESPONSIBILITIES OF AUTHORS

Before submitting a manuscript, authors should ensure that:

✓ The manuscript represents original scholarly work.

✓ All direct quotations are clearly identified and properly cited.

✓ Paraphrased ideas are appropriately attributed.

✓ Previous publications by the authors are properly cited.

✓ Sources of legal provisions, judicial decisions, and official documents are clearly identified.

✓ Copyrighted third-party material is used appropriately.

✓ The manuscript has not been submitted simultaneously to another journal.

I. SELF-PLAGIARISM AND TEXT RECYCLING

Authors should avoid substantial reuse of text, arguments, data, or other material from their previously published works without appropriate citation and disclosure. Limited reuse of standard methodological descriptions or related material may be considered acceptable where justified, but the submitted manuscript must contain sufficient originality and a distinct scholarly contribution.

J. PLAGIARISM IDENTIFIED AFTER PUBLICATION

If credible evidence of plagiarism or significant unattributed overlap is identified after publication, the Editorial Team will assess the matter in accordance with the journal's Publication Ethics and related policies.

Depending on the seriousness of the issue, the journal may:

Request an Explanation
Issue a Correction
Publish an Editorial Notice
Retract the Article

Appropriate action will depend on the extent, nature, and effect of the identified misconduct on the integrity of the scholarly record.

K. SIMILARITY CHECK AND PEER REVIEW

Passing a similarity check does not mean that a manuscript is automatically accepted for publication. The similarity screening process evaluates textual originality and potential ethical concerns, whereas the peer-review process independently evaluates the manuscript's academic quality, methodology, legal analysis, originality, relevance, and scholarly contribution.

L. EDITORIAL AUTHORITY

The final determination of whether textual similarity is acceptable rests with the Editorial Team of NUSALEGIS. Similarity percentages are interpreted together with the manuscript context, citation practices, sources of overlap, field-specific characteristics, and the journal's publication ethics standards.

Originality Matters

By submitting a manuscript to NUSALEGIS: Journal of Legal Studies, authors confirm that their manuscript is original, properly acknowledges relevant sources, and complies with the journal's standards of academic and publication integrity.
