Blemished Firstlings and the Limits of Judicial Liability

How the Sages regulate the maintenance, unauthorized inspection, and slaughter of a firstborn animal, alongside the restitution owed by erring judges.

Maintaining a Blemished Firstborn Animal

A kosher firstborn male animal (בכור - bekhor) possesses innate sanctity and belongs to the priest (כהן - kohen). If it develops a permanent blemish, it may be slaughtered for food rather than sacrificed on the altar. The Gemara inquires how long an owner or kohen may keep the animal alive before slaughtering it. In our era, an unblemished בכור may be maintained for several years until an eligible blemish appears.

Once a permanent blemish appears within its first year of life, the owner may keep the animal for the duration of that year. If the blemish appears fewer than thirty days before the year ends, the owner receives a completion period extending thirty days from the blemish. If the blemish develops after the first year has already elapsed, the animal may only be kept for thirty days.

The Rambam rules that a blemished בכור must be given to a kohen, who may eat or sell it as ordinary property. Both the Rambam and the Shulchan Arukh rule that an unblemished בכור today may be kept indefinitely until a blemish appears,. If the blemish occurs within thirty days of the year's close, the owner may maintain it for thirty days from the blemish, completing the count into the second year,.

נוֹלַד לוֹ מוּם בַּחֲמִשָּׁה עָשָׂר יוֹם בְּתוֹךְ שְׁנָתוֹ, מַשְׁלִימִין לוֹ חֲמִשָּׁה עָשָׂר יוֹם אַחַר שְׁנָתוֹ.

If the animal developed a blemish fifteen days before the end of its year, one completes for it fifteen days after its year. (Bekhorot 28a:9)

Slaughtering Prior to Expert Examination

The Mishnah examines a case where someone slaughters a בכור without prior authorization and only afterward presents the blemish to a qualified expert. Rabbi Yehuda permits the meat if the blemish is genuine, while Rabbi Meir forbids it because it was slaughtered without authorization. The Gemara clarifies that eye blemishes (דוקין שבעין - corneal cataracts) alter after death, making post-mortem verification impossible according to all authorities.

Regarding bodily blemishes (מומין שבגוף - mumin she-baguf) that do not change after death, the Sages disagree whether to penalize the owner. Rabbi Meir strictly penalizes anyone who slaughters without prior expert inspection to prevent inadvertent consumption of invalid animals.

The Rambam codifies Rabbi Meir's ruling: even if the blemish is obvious and unalterable, the slaughtered animal is prohibited and must be buried. The Shulchan Arukh rules identically, prohibiting any בכור slaughtered without prior authorization from a recognized sage or a lay tribunal of three men (שלשה בני הכנסת - shelosha benei hakeneset).

Liability of an Unqualified Inspector

If an unqualified person (מי שאינו מומחה - mi she-eino mumcheh) inspects a בכור and permits it, the slaughtered animal must be buried. Because this inspector caused the loss of the animal, he must pay monetary restitution to the owner. The Gemara records a baraita stating that he pays one-quarter of its value for small livestock and half its value for large livestock.

The reduction for small livestock was instituted due to the rabbinic decree discouraging the breeding of small livestock in Eretz Yisrael. Because owners were discouraged from grazing sheep and goats there, the Sages curtailed the inspector's liability to a quarter of the animal's worth.

The Rambam codifies this literally, ruling that the non-expert pays one-quarter for small livestock and half for large cattle. The Shulchan Arukh modifies this for current practice: outside Eretz Yisrael and nowadays, he pays half for small livestock as well as large cattle, because Jewish fields are no longer widespread and the grazing restriction is not enforced.

כְּשֶׁהוּא מְשַׁלֵּם — מְשַׁלֵּם רְבִיעַ לַדַּקָּה, וּמֶחֱצָה לַגַּסָּה. מַאי טַעְמָא? אָמַר רַב פָּפָּא: זֶה הֶפְסֵד מְרוּבֶּה, וְזֶה הֶפְסֵד מוּעָט.

When he pays, he pays one-quarter for small livestock, and half for large livestock. What is the reason? Rav Pappa says: this is a great loss, and that is a small loss. (Bekhorot 28b:6)

Judicial Erring and Expert Protection

The Mishnah extends liability principles to judges who issue an erroneous ruling that inflicts an irreversible monetary or ritual loss. A non-expert judge who causes direct loss must pay from his own property. However, a judge recognized as an expert by the court (מומחה לבית דין - mumcheh le-vet din) is entirely exempt from paying restitution.

This exemption is demonstrated by Rabbi Tarfon, who mistakenly declared a cow without a womb to be invalid (טריפה - tereifah), causing it to be fed to dogs. When Rabbi Tarfon thought he was obligated to pay for the cow, Rabbi Akiva exempted him because he was a recognized expert. The Gemara explains that while an error in an explicit rule (טעה בדבר משנה - ta'ah bi-dvar mishnah) is nullified, an error in legal discretion (שיקול הדעת - shikul ha-da'at) protects the authorized expert from monetary liability.

The Rosh affirms that an authorized expert who errs in legal evaluation is exempt from making compensation if the ruling cannot be reversed. The Shulchan Arukh and Rema's formal codifications of judicial liability in Choshen Mishpat are not supplied for this passage.

A firstborn animal slaughtered without expert inspection is permanently forbidden, while authorized judges are shielded from restitution when erring in judicial discretion.
