The Crucial Role of Astronomers as Expert Witnesses in Court Cases
Where was the Sun? Here’s why astronomers are more useful in court cases than you’d think In courtrooms across Australia, astronomers have been called upon over the past eight years to provide astronomical evidence in various legal proceedings. While eyewitness testimonies, DNA analysis, and police reports often come to mind when we think of evidence, expert witnesses are essential for explaining complex findings and data to help the court make informed decisions. Although expert witnesses typically come from fields like medicine, engineering, or psychology, astronomers have found themselves playing an unexpected role in the courtroom.
Astronomers as Expert Witnesses:
A Surprising Request The first time I received a request to provide astronomical evidence in court, I was taken aback. I had never considered the application of astronomy in a legal setting. However, as word spread about my capabilities, more and more requests poured in from colleagues within the same police force or division, as well as investigators who had heard of my work elsewhere. Now, on average, I am asked to submit evidence for approximately 1–2 cases per week. While some cases require a statement of evidence, others require my presence in court to explain the implications of the evidence.
The Significance of Astronomical Evidence
When I am called upon as an expert witness, it is usually for cases of great consequence. My evidence either plays a critical role in a specific aspect of the case or the case itself is significant, warranting thorough scrutiny and verification. But what exactly do I provide evidence for?
Tracking the Sun and the Moon: Shedding Light on the Truth
Astronomical evidence in court often revolves around calculating the positions and lighting conditions of celestial bodies such as the Sun or the Moon. Fortunately, the tools we employ for determining the positions of these celestial bodies are highly accurate and allow us to calculate their past or future locations for hundreds to thousands of years.
For instance, consider a scenario where someone claims the Sun obstructed their vision, leading to a car accident. In such cases, it becomes crucial to determine the precise position of the Sun, how it aligned with the street and the direction of travel, and whether it could have indeed impeded visibility at that specific time and location. Similarly, in situations where an event occurs around sunrise or sunset, an expert is needed to assess the lighting conditions. The Sun's position below the horizon and other factors play a role in determining the visibility levels. For example, if an event transpired five minutes after sunset, the available light depends on various factors, including the time of year and the specific location. Thus, discerning between daytime and nighttime is not always straightforward.
The Moon also plays a significant role in court evidence. Particularly in dark areas away from city lights, astronomers can provide valuable insights into the amount of light the Moon provided on a given night. Historical cases or instances where people rely on the view or phase of the Moon to establish when an event occurred also benefit from astronomical expertise. While the full Moon has a precise definition, there are times when the Moon appears nearly full, despite not technically being so.
Expertise and Its Limitations: Navigating the Complexities
Like any scientific discipline, astronomy has its limitations when it comes to providing evidence. Factors such as the refractivity of windows or the presence of clouds that might have obstructed the view of the Moon or the Sun need to be addressed by other experts and parts of the legal system. It is crucial to recognize that space technology, including satellites, is rapidly evolving and significantly impacting law and crime investigations. Satellites, such as those operated by space technology company Maxar, offer high-resolution imagery of Earth, aiding in the monitoring of various events. For a reasonable cost, individuals can request satellite images of specific areas and times.
Satellite imagery has already played a crucial role in several criminal investigations worldwide, including tracking troop movements and providing evidence of alleged war crimes. In Australia, satellite imagery is increasingly utilized in criminal cases, requiring the assistance of experts to interpret and explain its significance.
The Indispensable Role of Experts
Working as an expert witness has provided me with a renewed sense of hope as I witness the lengths to which the justice system goes to ensure accuracy, even considering factors like the Moon's phase or the Sun's position. This underscores the vital importance of experts in our society. In an era of rampant misinformation, it is crucial that people seek accurate and trustworthy information from reliable sources. Through expert witnesses, fields like space and astronomy can directly impact people's lives, even within the confines of a courtroom.
Conclusion:
Astronomers Shining a Light on Justice As astronomers take on the unexpected role of expert witnesses, their contributions to court cases have become increasingly valuable. By utilizing their expertise in calculating celestial positions and lighting conditions, they shed light on critical aspects of legal proceedings. While acknowledging the limitations of their field, astronomers work in tandem with other experts and evolving space technologies, such as satellites, to provide a comprehensive understanding of the evidence. Their involvement underscores the significance of expert knowledge in our society and emphasizes the need for accurate information in the pursuit of justice.
