Relationship evidence

Relationship evidence is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Relationship evidence rather than just read about it. In short: In law of evidence, relationship evidence describes a particular class of circumstantial evidence, defined in Australian jurisprudence as that which explains the "nature of the relationship between the complainant and the defendant". It provides a context for the offending behavior.

Key takeaways

Relationship evidence belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Relationship evidence to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Relationship evidence from memory before moving on to harder problems.

Reference excerpt

In law of evidence, relationship evidence describes a particular class of circumstantial evidence, defined in Australian jurisprudence as that which explains the "nature of the relationship between the complainant and the defendant". It provides a context for the offending behavior. Similar to tendency evidence, it establishes the tendency to commit an offence, usually multiple minor instances that often go unreported. The nature of the relationship is often obtained from witnesses who are extraneous to the offences charged. Another form of relationship evidence relates to the establishment of a relationship for the purposes of claiming a benefit of some kind.

Admissibility The admissibility of this type of evidence derives from common law principles that stand outside the direct operation of the Uniform Evidence Acts ("UEA").

Other types A different form of relationship evidence is used to establish a relationship for the purposes of obtaining some form of government benefit. In this case the best proof of relationship is a certified copy of the civil or religious birth record of the person filing for benefits showing the parents' names. When the relationship involves a legally adopted child or the parent of a legally adopted child, the best proof is a certified copy of the decree or order of adoption.

Worked examples

Example 1 — a first encounter with Relationship evidence

Start with the simplest possible case. Write down what Relationship evidence claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Relationship evidence before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Relationship evidence ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Relationship evidence

In research: Relationship evidence appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Relationship evidence in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Relationship evidence is common in secondary-school and first-year university syllabi. It links to neighbouring topics Evidence law, Law stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Relationship evidence outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Relationship evidence in simple terms?

Why does Relationship evidence matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Relationship evidence?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
