Thesis Air and Space Law


Admission requirements

Admission to the full time and parttime Blended Learning advanced LL.M. programme in Air and Space Law.


Students must write a thesis based upon a dedicated research conducted under the supervision of an academic staff member. On finishing all of the required courses, each student must submit a thesis of 15,000-20,000 words, plus table of contents, bibliography and annexes, on a topic of their interest. The topic is to be approved by the supervisor concerned. More information on thesis requirements and procedures is made available on Brightspace.

The thesis must address and analyse a substantive issue in air law or space law. It should not be merely descriptive, but rather analytical, well researched, and must demonstrate the student’s ability to synthesize the subject matter and relevant sources. The thesis should adopt an adequate methodology and ideally be of publishable quality.

Course Objectives

Upon completion of the thesis, students should be able to:

  • Conduct substantial, academically sound research on a topic in the area of air law or space law.

  • Present their research findings in writing in a clear and structured way.

  • Investigate and present new and innovative findings, where possible.


The timetable and deadlines are communicated via Brightspace.

Mode of Instruction

The students are guided initially by the Academic Coordinator on legal research and writing skills before they are directed to a supervisor who has specialist knowledge regarding the chosen topic or area. Students and supervisors meet to discuss the research. Supervisors provide written feedback on an outline of the thesis and an early draft.

Assessment method

The thesis is graded by the supervisor and moderated by a second reader. The thesis is successfully passed if a grade is obtained of 6.0 or higher. Only one retake may be granted to a student per course.

No retake will be granted to a student who has obtained a weighted average grade for the course of 6.0 or higher, cf Article 12.2 Course and Examination Regulations. No retake will be allowed if a student has not taken the scheduled exam, or any other scheduled form of assessment, and handed in written proof of a conscientious effort to meet the deadline. This is without prejudice to justified reasons of health, family or any other force majeure that could prevent the student from attending class or from participating in the assessment, cf. Article 12.3.

The grade obtained in the retake assessment will replace the grade of the failed assessment.
