Issue with civil law case law title in single citation

[f-mb]

Transferring zotero/zotero#893 here.

Hi,

When you cite two (or more) "civil law case law" in a single citation, except for the first, court name and date are omitted.

Individual Citations :
CJCE, 31 mai 1978, C-102/77, Hoffmann-La Roche / Centrafarm, Rec. 1978.1139.
CJCE, 17 octobre 1990, C-10/89, CNL-SUCAL / HAG (HAG II), Rec. 1990.I‑3711.
(FYI: court, date, docket number, short title, reporter reporter volume.first page.)

Single Citation :
CJCE, 31 mai 1978, C-102/77, Hoffmann-La Roche / Centrafarm, Rec. 1978.1139; CNL-SUCAL / HAG (HAG II), Rec. 1990.I‑3711.

Should be :
CJCE, 31 mai 1978, C-102/77, Hoffmann-La Roche / Centrafarm, Rec. 1978.1139; CJCE, 17 octobre 1990, C-10/89, CNL-SUCAL / HAG (HAG II), Rec. 1990.I‑3711.

I think the issue is with citeproc.js around lines 4197-4203 [edit: now around 5224-5225].

I know there is a hook with for case. Multiple citations of a case law items with the same title will be merged into one.

I guess the issue is that every "civil law case law" has technically an identical title : ""/false.
(reminder: civil Law format, in Zotero at least, is created by omitting the title field in favour of the short title field)

A fix would be for citeproc to first check if there is any title at all...

Thank you.

I think the solution would be at line 5224:
if (title !== "" && type === "legal_case" && id !== lastID && position) {
where title !== "" test if title is empty (similar to the test at 10121)

Florian (@f-mb): Sorry for the very long delay in getting back. I would like to straighten this out. Two belated questions to set up a test:

• Would you have reference data to hand (exported in CSL JSON format)?
• Which style should be used?
