Follow the lineto its axis.
Spes Jurisp is the map of the lines of case law. It shows how judgments cite and hold each other up, which precedent serves as the axis of a line, and which family of judgments would be left unsupported if that precedent were overturned. It does not predict how a court will rule: it illuminates the structure of precedent. The reading is done by the lawyer.
Structure, not forecast
It does not attempt to guess the outcome of a case —there the court decides and the lawyer argues—. It reads how judgments connect to one another. That is why what it asserts is concrete and traceable back to the source: it is not a prediction, it is the position of a judgment within the network of precedent.
What it does
It illuminates the architecture of precedent and its evolution.
The line and its axis
It shows how judgments cite, follow, distinguish or affirm one another, and which is the leading case on which a line rests.
What loses support
If a precedent of high weight is overturned or weakened, it flags which family of judgments is left without support.
The bridging judgment and the line over time
It detects the judgment that connects two lines which would otherwise not touch, and shows which doctrine consolidates or is abandoned over the years.
Stated or to be confirmed
It distinguishes the relationship expressly cited in the judgment from the one inferred without a citation, and marks the latter as a reading to be confirmed. It never invents a relationship the source does not support.
What it does not do
The boundary is clear, and that is what keeps it reliable.
It does not predict the ruling
It does not anticipate how a court will decide, nor the outcome of a case.
It does not interpret
It does not say what the precedent means, nor whether it is rightly decided.
It does not advise
It does not recommend a litigation strategy. That belongs to the professional.
The structure is asserted; the law you apply yourself
The system delivers the map of precedent and its fragility, measured and traceable. What that structure means for your case, and what to do with it, is the lawyer's decision.
