Paste cases with years and get a sorted timeline showing how doctrine developed. Free, no sign-up.
What this tool does
Doctrine is a story told in dates: an early case states a rule, a later case narrows it, a still later one overrules it. Lists hide that story; timelines show it. Paste cases as ‘Year | Case | Note’ and this linker sorts them, spaces them on a line, and marks each case’s note — affirmed, narrowed, overruled — so the development of a legal idea becomes something you can see and explain, not just assert.
Why it matters
Good citations do quiet work. They let a reader find every source you used, they show that your argument rests on real evidence rather than memory, and they protect you: a clean reference list is much harder to challenge than a vague one. Most marks lost on referencing are not lost on difficult sources. They are lost on small, repeated slips — a missing year, a swapped initial, a title in the wrong case — that a quick tool pass catches before submission.
How to use it
- Paste cases: Year | Case name | Note (one per line).
- Click Build timeline.
- Read the sorted timeline.
Worked example
‘1954 | Brown v. Board of Education | Overruled segregation’ and ‘1896 | Plessy v. Ferguson | Established separate but equal’ sort into 1896 first, then 1954, with a 58-year gap labelled between them. The gap itself tells part of the story.
Tips for good results
Add the overruling case as its own entry. A timeline that ends at the overruled case tells the story backwards.
Work from the source itself, not from another paper’s copy of it. And keep one style for the whole list: a single mixed entry undermines an otherwise perfect bibliography.
Honest limits
The timeline orders by the year you give and trusts your notes; it does not verify case dates, holdings or overruling relationships. A wrong year produces a confidently wrong timeline — check dates against a case database before relying on the picture.
Common mistakes to avoid
Common mistakes to avoid: copying a reference from another paper without checking it against the original, trusting a PDF filename for the title or year, and mixing two styles in one list. Each of these looks harmless alone and careless together. Run the tool, read its output once, and compare it with the source itself before you paste it into your document.
Before you submit
Run through this short check before you submit: is every author name spelled as it appears on the source, is every year present and correct, and does every in-text citation have a matching entry in your reference list? Read the list once from top to bottom rather than skimming it. Most referencing errors are found in that single slow read, and fixing them there is far cheaper than fixing them after a reviewer finds them. If one entry still looks odd after that read, check it against the original source before you change anything else.
Frequently asked questions
Is this tool really free?
Yes. It runs in your browser on this page, with no account and no payment. Nothing you paste leaves your computer.
Do I still need to check the result?
Yes, once. Tools apply rules; they cannot verify facts about your source. Compare the output with the source itself before submitting.
Can I use the output in my paper?
Yes. The output is a formatted reference or analysis for your own work. Keep the source’s facts accurate and the formatting consistent across your list.
What if the tool’s output differs from my style guide?
Trust the style guide. Tools encode the common rules of a style; your university or journal’s own sheet wins every disagreement. Use the tool to do the routine work, then apply the local rule where it differs.
